Daisy Dam Covers

Daisy Pool Covers recently released a Dam Cover range so that property owners can stop evaporation in their dams (where the water is covered).

Daisy recommends using the Dam Cover across most of the dam surface area and letting if float around, but not covering all of the dam so that water can still flow in, and livestock can still access the water as well as allowing rain to drain off the cover and into the dam.

Dam Covers ReadyDaisy has been quite busy since the Dam Covers range launched and they recently travelled to Dwellingup, WA to install a set of Dam Covers for customer Rob Hill.

They installed 5 of the 5.2 x 5.2m dam covers onto one dam and one Rob’s second dam.

Rob knows the evaporation rate in his dams and has been looking for a way to stop evaporation for a number of years now and he came across the Daisy Dam Cover on the Daisy website. Knowing that a physical barrier will simply stop evaporation, he knew the Daisy Dam Cover would work on his property.

Rob said the covers were well-priced and so he ordered 6 to see how they would go.

When the Daisy team arrived to install the dam covers, Rob saw how easy they went on and the coverage they gave the water. For a physical barrier that will stop the evaporation, Rob thought they looked great!

The second dam only had one cover ordered and installed but after seeing the rest of the covers on his larger dam, Rob has ordered another 2 dam covers that he will install himself, after watching the Daisy team install the others.

Rob said, “It may not solve all my water problems, but it will definitely improve my situation. I’ve been looking for a solution for many years, and I think I’ve found it.”

With the white top and black bottom, a Daisy Dam Cover is not going to heat up the water. If anything, it’s going to help with algae growth. Rob thinks with his dams that the covers will stop some of the sunlight so the algae can’t grow as much.

Rob also said, I left it a bit late. I should have really put the covers on at the end of winter to stop the water loss but hey, at least I have done it now.”

Daisy Dam Cover

When the dam fills again (and the water rises) Rob said he will be right on the phone to order more covers. With the modular system of the Daisy Dam Covers, Rob said he wants to cover what surface area he can, so he saves as much water as possible.

Rob said he has spent so much money on the dams over the last 30 years and this is the first time he has been able to find something long-lasting that will stop the evaporation.

Rob can see plenty of people going for this style of Dam Cover to stop water loss and still allow animals and farmers access to the water.

Daisy Dam Covers are robust, but you must still be careful about anything sharp underneath the covers. A simple process makes it easy for any property owner to install: unfold, set up, tether together (if you wish) and then pull into place on the dam surface.

Interesting Installations #2

In the lead up to December the team was busy out there installing new pool covers and rollers all around Australia. Some are straightforward, others are more of a challenge and we love that!

Breathable Pool Covers?

Breathable Pool Covers?

Recently, the industry has seen the introduction of a so-called “breathable pool cover”. At Daisy Pool Covers, we were intrigued by this new pool cover with holes punched in it and thought we would explain what they do and how they work. While many may think that “the latest product is usually the greatest”, we did our homework to discover what makes them different, or not so different to the market leading solar pool covers that Daisy have been producing since 1983.

Taking a close look at this new breed of pool cover, they are designed with holes punched though the cover. The covers benefits claim that when you allow your pool to breath, it results in a  cleaner, longer lasting pool and a healthier swimming environment. What the team at Daisy Pool Covers discovered was no matter what type of pool cover you purchase, there is absolutely no alternative to looking after your pool’s chemical balance and uncovering your pool water once in a while.

The key to longevity in your pool cover, surface and equipment is keeping your chemical balance consistent. If you keep your pool water balanced, as recommended by SPASA Australia, you will not reduce the lifespan of your equipment, pool surface or pool cover. Not only will it save you money in the long run (out of balance water can cause expensive damage to your pool), but your swimming experience will be so much better without your pool being unbalanced or dangerous to swim in.

The Daisy Day was designed to educate pool owners to remove their pool cover to let the pool breathe and test the pool water. This is to ensure pool owners are keeping an eye on their water balance, to make sure there isn’t an imbalance, causing damage to their cover or equipment down the track. The Daisy team works hard to actively promote best practice pool and pool cover usage to prolong the life of all pool surfaces, pool covers, equipment; giving customers the best swimming experience possible.

What does a breathable pool cover do?

A breathable pool cover is meant to release gases from the pool water into the air through tiny holes punched into the pool cover, whilst stopping evaporation of pool water. We’ve taken a look at the claims made by breathable pool covers and given our own opinion based on industry knowledge, research and testing out in the field.

A “breathing” pool cover won’t be able to correct an out of balance pool. Fibreglass resin suppliers, along with the swimming pool industry, know that without correct water balance you will get a myriad of problems from damaging the pool’s surface to shortening the life of pool equipment (covers, pool cleaners, pool toys – anything the water comes into contact with) as well as a potentially dangerous swimming environment.

Pool covers don’t cause incorrect water balance, and they cannot fix it either. Best practice is to use a pool shop that you trust to regularly check and maintain the water chemistry.

A misconception not widely known, is all pool covers are technically breathable. They are made of Polyethylene (PE) a material that by its chemical nature naturally allows a gas transmission rate for oxygen, carbon dioxide and other gasses including chlorinated gases. There been a huge amount of research completed by Sealed Air (the inventor of original bubble wrap and solar pool covers) that shows that PE pool covers do actually breathe. For a 500 micron pool cover, the oxygen transmission rate would be approximately 500cc/m2 per 24 hours at 23°C, meaning PE pool covers do naturally ‘breathe’.

Sealed Air (the Australian company that make Daisy Pool Covers raw materials on Daisy’s dies) invented the Bubble Wrap technology, and believe me, they know their stuff, especially when it comes to the ins and outs of “Moisture Vapour Transition Rate” (MVTR) and the “Oxygen Vapour Transition Rate” (OVTR). The origional bubble wrap was designed with a Nylon barrier layer to stop the air and other gasses moving through the material to avoid the packaging bubbles deflating during use. The pool cover formulation was redesigned to allow the pool cover material to naturally breath, without requiring additional holes.

Breathable pool covers still need to be removed regularly, like all other pool covers; they aren’t a set and forget option like they might appear. Pool owners will still need to remove their pool covers, no matter which one they buy, to ensure they are regularly testing their pool water and retain chemical balance in the pool.

The FAQ section from the breathable pool cover website states: 

It is not recommended that any solar blanket be left on a pool permanently. Aquavent is no different in this respect and should be removed for maintenance as per the Maintenance Guide.

Pool owners should be checking the following regularly:

  • Chlorine level
  • pH
  • Total Alkalinity
  • Calcium Hardness


Please click here for more information on swimming pool water balance.


Breathable Pool Cover Testing

Let’s look at the testing methods and results that have been conducted by Aquavent.

First Test

The testing done on the “breathable pool covers” included the following:

  1. 3 small tubs with no specified volume
  2. Added approximately 2.5mg/L of granular pool chlorine
  3. Measured chlorine levels over 7 days


  • 97% chlorine loss over 7 days with Aquavent pool cover
  • 96% chlorine loss in an open tub (no cover)
  • 62% chlorine loss with a Daisy cover
  • pH levels roughly the same
  • Water temperature is warmer with a Daisy pool cover (20.1 degrees) than with Aquavent (18.3 degrees) and no cover (17.8 degrees)

Using an Aquavent “breathable pool cover” does not keep chemicals in the pool nor does it keep the water warm. They claim that a Daisy Pool Cover has a higher pool chlorine level, that adding a normal dose of chlorine each week will result in over-chlorination of the pool. This finding doesn’t take into account the fact the pool owner would be dosing their pool based on pool water testing. If the chlorine levels were adequate, no chlorine should be added. In fact, the testing indicates to the contrary. You will need to use more chemicals with an Aquavent cover than you do with a Daisy pool cover to properly maintain the pool water. AND, you will need to consume more power to maintain the water temperature

Second Test

The test was conducted similar to the first test, but the initial water chlorine level was 5mg/L.

Then each day, an additional 2.5mg/L was added. Because chlorine doesn’t escape as much with a Daisy cover, after 7 days the Daisy sample had 8.7mg/L of chlorine prior to the final dose, versus the Aquavent cover which had 3.1mg/L.

The average chlorine loss per day for Aquavent was 39% versus Daisy at 15% and no cover had 21% loss.

The odd result from this test is that Aquavent covers had a HIGHER loss of chlorine than if you had no pool cover at all!

The final test was water transmission for evaporation:

  • Daisy was 0.03g/h.m2 (grams per hour per square metre).
  • Aquavent was 0.26g/h.m2
  • No cover/open tub was 67g/h.m2

In essence, Aquavent has a water transmission rate (evaporation) is 8.66 times greater than Daisy.

Overall findings from testing

  1. The so-called “breathable” pool cover testing indicates the Aquavent cover will maintain chemical levels lower than an uncovered pool. This just isn’t possible as it would mean you would go through MORE chlorine than with a completely uncovered pool.
  2. In the Aquavent testing, there is no allowance for testing water or adjusting the water balance. Some level of dosing will always be required in a well-managed pool. The testing regime undertaken is continually adding chemicals to the water without any rationale to test the water to see what dosing is required.
  3. The Aquavent FAQs state that they are no different to other solar pool covers and no pool cover should be left on permanently. They state that pool covers should be removed for pool maintenance for as per their Maintenance Guide.

The FAQs also warn, pool damage can still occur through poor pool maintenance.

Additional Testing 

July 17th – Installation Day
July 18th
August 7th, no rain.
August 15th, no rain.
August 18th, no rain.

As you can see from the photos of the Aquavent pool cover, there is water sitting on top of the pool cover (over one month without rain, you can see from the day the cover was installed there is no water on top). The day after installation, water was pooling on top of the cover and then showing the same amount of water on top after 3 weeks and then 4 weeks.

This means:

  1. Evaporation rate for 100% where water sits on top of the cover as water is evaporating, then re-filling (supposedly seeping through the “breathing holes”).
  2. Insulation and heat saving are zero where the water is sitting on top of the cover. Heat transference is dissipated through the water surface. If there is a cover or membrane that has water on both sides, there is zero insulation. Traditional solar covers get some water on top of the cover during operation or rain but that either drains into the pool or evaporates quickly which will leave no water on top of the cover.

Water Ingress into the Bubble Hole

Simple testing of the Aquavent shows the vent hole sits in the water. When we put a sample piece of the cover material on the water the ‘vent and drain’ bubble was touching the water. This means (according to Aquavent themselves) that the vent hole touching the water would make the ‘venting’ of chlorine or any gas trapped in the pocked under the cover redundant.

Holes sitting on the water

Water seeps through the cover and sits on top (see photo below). Water also can’t drain out of the bubble if the hole at the bottom is touching the water. You can see by the image below that the water can’t drain from the ‘vent and drain’ bubble as it is in the water. If the chlorine dissipates through the holes but water remains in the bubble, it’ll be untreated and may well turn green.

This simple test showed that after a relatively short period of time without being in the swimming pool environment water did enter the bubbles through the vent holes that they were supposed to drain out from

This would also bring into question how heavy the cover will become with all the water that cannot drain out. The small sample was significantly heavier with the retained water. A traditional cover (without holes) will increase in weight by approximately 50% with water hanging on the outside of the bubbles as they are removed off the swimming pool. Pool covers with holes that retain water in the bubbles will dramatically increase the weight of the pool cover.

Water on top of Aquavent cover exactly 4 weeks after installation with no rain.

With water being retained in these holes, a build-up of debris, dust and salts will occur over time, stopping any perceived benefit that these holes may have.

Water in the pool cover bubbles

In conclusion, Daisy does not believe there is any net gain from having a pool cover with holes punched into it. Daisy, along with industry leaders, believe the breathable pool cover is like a square wheel, great to be new in the industry, but it just does not perform to the standard that Daisy Pool Covers sets for itself.

It’s a WinterKleen winter

Hands up anyone who loves leaves and constantly cleaning their pools!  No? It’s WinterKleen time.

Your clients will just love you if you can help them keep the leaves out of their pool all winter long!

With parts of Australia cooling down along with a seasonal change there is an increased demand on covering and protecting the pool from leaves, dirt and rubbish entering the pool.

The Winterkleen has long been the go-to answer for pool owners who experience high debris problems, and this year is no exception.

By covering the pool with the porous Winterkleen material all the dirt stays out of the water while letting the water pass through. So keeping the debris out of the pool it makes your customers life much easier and they love their pool (and you) a little more.

With a Winterkleen it makes looking after the pool so much easier. And this year we have had an increased demand. It’s ok – we are still custom making the covers and dispatching them in a matter of days!

The new Black Winterkleen has been a remarkable hit, steady sales of the new product has validated the latest addition to the range.

Know how to measure for a rectangular or a shaped Winterkleen pool cover? If you need a hand, feel free to give your local Area Manager a call.

Contact the Admin Centre or have a look at the How To videos here.

Importantly, let your customers and database know you have these products available, there may be sales waiting for you that you don’t know about!

Does the whole pool need to be covered?

Daisy makes it easier

When there are obstructions or irregular shaped pools, a question we are often asked is: how will we make it work?

For the customer this question can be for a number of reasons, their pool may be:

  • Free form pools that have a very irregular shape
  • Large step areas (or sections) that protrude in an unusual way
  • Step areas (or sections) that are inaccessible
  • Posts or pots obstructing the use of a roller
  • Not enough room for a roller full width.

Daisy CAN help (it’s even easier if you send a photo)! The aim of making a pool cover easier to use is so that the customer will actually use their pool cover.

If the pool cover is too hard to use then they will tend to leave it to one side and not worry about using it.

To make pool covers more user friendly, we may advise not to cover the whole pool area. It is ok to leave some parts uncovered for ease of use.

For some shapes we will advise to leave a section uncovered, the heat loss (lack of insulation) or lack of heating, and even the evaporation is a direct ratio of how much of the pool is covered to how much is uncovered.

The evaporation can only occur on the uncovered section, so if you have 95% of the pool covered they are stopping 95% of the evaporation. The trade-off for the small amount of evaporation far outweighs the customer actually being able to use the pool cover.

Sometimes the shape of the pool will equal the usage and the advice. Send a photo to Daisy for assistance and expert advice if your customer is ok for you to defer the advice to your supplier for special or unusual installations. Email us at hello@daisypoolcovers.com.au

Are you losing pool water over summer?

How to test if it’s a leak or evaporation

At this time of year with the heat of summer many pool owners think they have a leak in their pool as they seem to always have a hose hanging in the pool and constantly topping it up.

We’ve seen hoses with white chlorine bleached ends where they have been hanging in the pool. The owners complain that the hose has to stay there as they are tired of pulling it out every second day to top up the water level.

To see if you have a leak or if the water being lost is simply from evaporation; it’s easy!

Put a full bucket of water by your pool and measure the height of the water in your pool (and record it for accuracy). Wait a number of days to a week then measure how far the water level in the pool and the water level in the bucket has dropped. They should both drop the same amount in millimetres as water evaporates at the same rate regardless of surface area (it is only the volume that is different).

To put this into perspective, let’s work out how much water you are putting in your pool:

  1. Most hoses run at about 17 litres per minute. If you have a hose running flat out for 30 minutes you are using just over 500 litres. If you are topping up your pool 2 to 3 times per week then you are using between 1,000 to 1,500 litres per week. Or around 4,000 to 6,500 litres per month… and that is only at 30 minutes, how long do you run your hose for?
  2. If your pool is 9.2m by 4.5m, for every millimetre the water level goes down is 41.4 litres. So topping your pool up from around 1/3rd way up the skimmer box to about ½ way say 25mm means you are adding 1,035 litres of water to your pool.

Evaporation rates are higher over summer

To stop evaporation, cover your pool with a Daisy. This is effectively putting a lid on your pool to stop the water loss, not to mention saving chemicals and helping keep your pool a bit warmer and cleaner.
Daisy pool covers have been independently tested to retain 99.9% of water using the ASTM E96-2005 Water Vapour Transmission test.

For more information including the different types of evaporation for capital cities around Australia and how wind can more than double the daily evaporation rate, read our Evaporation Fact Sheet.

Approaching Winter and Rain: Your To-do List

Winterising your pool in four quick steps.

Changes in weather conditions bring along change to your swimming pool water balance.

 It’s important to bare this in mind as we lead into the winter season when we trade splashing around in the water for huddling in front of the fireplace. Dramatic changes to your pool water levels can cause havoc to your water chemistry, especially when you add leaves to the equation. Rain, leaves and other organic matter can add a whole new dimension to the water environment.

What happens to my pool when it rains? When more (or less) rain water lands in your pool it changes the overall chemical concentration. Put simply, the rain dilutes your pool chemical concentration. The more rain you have in your pool, the more the fresh water will dilute the salt and chlorine levels.

Four steps to winterising your pool

  1. Make sure your chemicals are balanced – use a test kit or pop into your local pool professional to get some sound advice
  2. Tidy your pool – clear any unwanted debris, toys or objects
  3. Drain the water out of your pool – keep the water level half to two thirds up your skimmer box
  4. Protect your pool with a pool cover!

Want to Save Time Cleaning Your Pool This Autumn?

Get the dirt on WinterKleen – all year round pool covers.

Uh huh we get it. Your have a heavy debris or dirt problem. You don’t want to spend hour after hour, weekend after weekend, slaving away cleaning your pool. And… you want a cover to help you keep the leaves and dirt out of your pool.

Well, we’ve got an industry-best product for you… a WinterKleen Pool Cover!

A WinterKleen pool cover is perfect, especially during these cooler wintery months.

 They save:

  • Leaves and debris entering pool
  • Time cleaning
  • Evaporation
  • Running costs
  • Chemical use
  • Water because it passes through
  • The pool from becoming a science experiment over extended periods of non-use.

WinterKleen covers are made with a fine polypropylene mesh that is strong to survive the elements and also lightweight for easy handling. This type of pool cover protects your pool from leaves, dirt and debris and also allows water through into the pool.

These covers work best when stretched over your pool during long periods when your pool isn’t being used. Leaves and dirt that fall on the cover can be blown or swept off the cover.

The finished cover stretches across your entire pool overlapping it by 20cms with tie down toggles about 80cms apart, anchored a further 20cms from the cover’s edge. The tie down toggles are easily pulled tight, one by one until taut.

WinterKleen covers are available in blue or green and are shaped with a square cut to fit over any shaped pool. Additional charges apply if you want the cover to mirror a shaped curvilinear pool as this requires a Daisy Expert to measure accurately.

A WinterKleen has an 8 year pro-rata warranty and is easily removed when it’s time to put on a Daisy solar pool cover. Treat yourself this autumn-winter season with a new WinterKleen!
