Hey everyone, it's matt from swim university and we are going to prove if the liquid solar covers actually keep your pool. Warm the sun helps water to evaporate from your pool. Now what liquid solar covers do? Is they actually limit that evaporation? Now with that evaporation? That happens in the middle of the night. When your pool is cooler it apparently you lose a lot of heat at the same time, what we're going to prove is that water will actually limit the amount of evaporation with a liquid solar cover and it will actually keep your pool warmer in order to prove That liquid solar covers actually work.

What we're going to do is an experiment: we're going to fill these two identical containers with water and blue food coloring, so that you'll be able to see it in this container. We're going to put the liquid solar cover that was sent to me by flexible solutions and in this we're gon na put nothing. Let's fill up these containers equally with water and blue food coloring. Next, we're going to add the heat saver liquid, which is the liquid solar cover to this container right here with the liquid solar fish in front of it.

Okay in this container, we've put the liquid solar cover and we've mixed it around a little bit to disperse the chemical, and in this container we put nothing so in theory, this container should not evaporate as fast as this one, so we'll be back in a short While and see what happens, it's been 48 hours since we've had these two containers outside here in the sun and now we're going to figure out if one evaporated faster than the other or evaporate it more than the other. Now, if we do a close-up here, we'll find out that both containers they've looked very similar, but it turns out that the container with the liquid solar cover inside of it didn't evaporate as much as the one. Without the big moment of truth, is we're going to find out which container has a higher temperature? Is it the container that doesn't have the liquid solar blanket in it or the container that does have the liquid solar blank in it? So we're going to use this digital thermometer to test the one that doesn't have the liquid solar blanket in it to read what the temperature is, and it turns out that this container has 80 degrees. It's at 87 degrees now to test the container that has the liquid solar cover in it, and it looks like this container is at 91.5 degrees.

No, i'm sorry! 91! Oh, it keeps climbing 92 degrees. So it turns out that the container with the liquid solar cover - and it is actually five degrees higher than the container without the liquid solar cover in it, and it also did not evaporate as much as the container without so it turns out that the solar liquid Solar cover does actually work, which is great, if you have any questions or if you, if you want to find out more information, you can visit our website.

    How can one person take so long to say something simple. Extreme phrase repetition. Annoying. Give a guy a white coat and he becomes an actor. He ruins your product!

  2. Avataaar/Circle Created with python_avatars DeeCee Douglas says:

    I see that this is safe to run through the filter, however, is it safe for the heater? We hope to heat our pool during the day, then put the liquid in the pool for the first time at night, and then possibly not have to run our heater for as long, during the rest of the week that we are having a family reunion at the end of March. Thanks for your help! Service area Orleans??

    Do you put the liquid cover directly into the skimmer Box

  4. Avataaar/Circle Created with python_avatars Kim McG says:

    Does the chemical have any negative effects on the water? (Like the smell, or the feel?) Is it greasy? Does it effect the water quality test? How safe is it for sensitive skin?

    Had hopes in this video but agree with comments below (inaccurate experiment, uninsulated containers, should use weight metrics rather than eyeball tiny differences between container lines). Would prefer to see: Larger, insulated, weighed containers, longer than 48 hrs test period, REAL Texas sun (what is this utopia — Oregon during Winter?!), and …. will it retain heat overnight: Our issue is chilly pool in the morning. It's plenty hot during the day.

  7. Avataaar/Circle Created with python_avatars Harold S. Goldsmith says:

    I currently have a retractable cover which I close when the pool is not in use. Would this Liquid Solar cover still help to retain additional heat?

  8. Avataaar/Circle Created with python_avatars Swim University says:

    Do you use liquid solar covers in your pool?

  9. Avataaar/Circle Created with python_avatars Linda B says:

    Using a liquid solar cover last summer noticeably reduced the evaporation rate of water in my pool (since I have to manually turn on the valve to add water, I notice how often and for how long I have to leave the valve on, and I carefully monitor my water usage as shown on my monthly water bill ….. it was obvious the evap rate was decreased because I did not need to add water so often and my water bill went down). I also tracked the temp before using vs when using vs when I ran out of it vs when using again … to the best of my tracking, it appeared to increase the pool water temp by ~4 degrees F (harder to determine that with great accuracy due to difficulty in compensating for the outdoor environmental factors) Are you in Barrhaven ?

    istead of buying a solar powered water heater for your pool, drain it a use waterproof black paint to paint a wide black line on the bottom of your pool, then refill and you'll have a solar powered pool heater that will last forever and never break.

    When added to water it produces a protozoan film that multiplies from sunlight heat. If left in extremely sunny climates it eventually becomes a mass of jelly like embryos. We are one we will not be contained. We are. We are. We are.

    Not safe for fish? Service area Barrhaven??

    if you want to know how to make some of your DIY kinds of stuff yourself, just go to an Avasva website. There you'll find your answers 🙂

    Bullshit

  16. Avataaar/Circle Created with python_avatars Valorie Wake says:

    We have a 27 foot round by 54 inch deep pool. We also live out on the open range in central Illinois. The liquid solar covers DO help keep pool warmer and eliminate evaporation. So, any person who is trying to mock this demonstration, shame on you. Try it before you knock it.

  17. Avataaar/Circle Created with python_avatars The_Godfather says:

    so this liquid does not heat the pool, it just helps eliminate evaporation right

  18. Avataaar/Circle Created with python_avatars MCGamer says:

    This is such a bullshit experiment from a professional pool store employee. There are too many variables to count. How much did you put in? Directions on the bottle say 4 oz. per how many gallons? Also didn't take into consideration lack of water movement. What happens when the water is sucked through the return side and back to the pool. No mention of water features and slides. There are very controlled "experiments" such as this idiotic sophomoric attempt. Then there are real world experiments. Matt, you're a joke.

  19. Avataaar/Circle Created with python_avatars Sausage Sandwich says:

    We had a liquid blanket in our pool for about 6 years dosing automatically.
    We ran out of the liquid one summer and didn't bother buying more to see what would happen and our evaporation and heat levels remained similar.
    The conclusion and our local pool guy confirmed this, that the moment the wind blew the liquid would go to one end of the pool, rendering it useless.
    Outdoor pool…waste of time.

  20. Avataaar/Circle Created with python_avatars Bete Noire says:

    Usually you don't state your conclusions prior to conducting the test.

  21. Avataaar/Circle Created with python_avatars M Angelica Gonzalez Huneeus says:

    what appens with the solar cover and the filter? dosent it clog the filter when cleaning the pool?

    Does it cause skin cancer?

  23. Avataaar/Circle Created with python_avatars tdopp89 says:

    My heater broke 3 years ago and I tried this.  Our last 2 summers here have not exactly been warm.  With this and a solar cover I have been able to achieve 84 – 88 degrees in my pool.  My pool is 16 X 24.  4 feet shallow end 5 1/2  feet deep end.  I run my pumps during the day they are shut off at night.  Here on the burbs of The Windy Cidy we get quite the breeze at times as well as wind.  The only time this has NOT been effective, was with the ton of rain we were getting here every other day this summer.  That, combined with a lack of sun made June pretty miserable as well as the first week of July.  Since summer finally decided to arrive, I have not been below 84 with 86 being average.  I believe it does work.  Would love to see how it works with a working heater 🙂

  24. Avataaar/Circle Created with python_avatars ReAp Commander says:

    My pool is 21 feet diameter and the bottle of liquid pool cover says use 1 for every 400 square feet, how many should I use?

  25. Avataaar/Circle Created with python_avatars SuperJoe says:

    My problem with this test is that Matt says "We are gonna prove that liquid solar covers will keep your pool warm" I would trust this more if he said "if they keep your pool warm". As we know from global warming, etc…any scientist can find any outcome they want, and seemingly "prove' it. I'll continue my search to see if these are worth trying, but since I have a waterfall on my pool, I'm assuming they will not due to the water movement during the day.

  26. Avataaar/Circle Created with python_avatars Super Speed says:

    I was told that water movement negates the products ability to make a layer on the top.  Since you did not have a water pump on for the experiment I think real pool results would be a little different.  Also how did you balance the amount of product in the liquid solar container.  Normally, you would put the product in a 10,000 plus swimming pool.  Did you determine a smaller percentage for the (relatively) tiny amount of water in the test?  That said, I did find the video interesting. Thank you.

  27. Avataaar/Circle Created with python_avatars Keith Anderson says:

    Easy way to check if one container lost more water than the other would be to weigh them. Weigh them at start to make sure same amount/weight of water, and then weigh at end. Weight is easier to check than volume. People who use the metric system know the direct correlation between water weight and volume 🙂

  28. Avataaar/Circle Created with python_avatars B0R0 says:

    For us foreigners, is that degree centigrade of Fahrenheit? Are you in Nepean ?

  29. Avataaar/Circle Created with python_avatars joeyunity says:

    great video. gonna give it a try. Living in the Northeast it costs a TON to keep a pool heated. I will post my results. Service area Ottawa??

  30. Avataaar/Circle Created with python_avatars Tjfreak says:

    Don't do it ! follow your gut,qualifies for the magic pill category.There are too many other real world variables,if it works it was incalculable & certainly not worth it Are you in Kanata ?

  31. Avataaar/Circle Created with python_avatars Mark Greer says:

    Would be very curious to know how much more heat a solar cover retains compared to the liquid.

  32. Avataaar/Circle Created with python_avatars Mark Greer says:

    Why not include a test with the solar cover? Paid not to?

  33. Avataaar/Circle Created with python_avatars Ric Palma says:

    The "disturbing jelly like thing(s)" are prob mosquito larvae which wouldn't occur in water with proper chlorination. Also mosquitoes would prefer the warmer water which might explain the absence of similar critters in the other (cooler) container.
