How Water Movement Effects Liquid Solar Pool Covers
by Monique Nelson on October 6th, 2009

One of the questions I get quite often is in regards to the efficiency of a liquid solar pool cover when there is movement in the water. This question comes in many forms:

  • “I have a pool vacuum...”
  • “What if my pump and filter system stay on...”
  • “I have a chlorine shark that swims around all the time...”
  • “I swim in my pool...”
  • “My kids leave pool noodles in the water...”

I'm sure you get the picture. Well, the simple answer is yes, these things will affect the liquid cover, BUT to such a minimal degree that you probably will not notice the slightest difference.

Basically, how the liquid cover works is by spreading a very thin layer over your pool water, which you will not see, smell, taste or feel and which is completely safe. When there is any movement in the water, be it a swimmer, a chlorine shark or a pool noodle, the product will move away slightly, and form itself around the item in the water. If the item is moving, the product will continually re-form itself behind the movement. As such, the product will still be working for you even if your pool jets are continuously running.

That's one of the nicest things about a liquid blanket—they are always protecting your pool from heat loss, even when you're in it, whereas a plastic or bubble pool blanket is only effective when your pool is closed and unavailable to you.

I hope this helps, but feel free to send me an email if you would like a more scientific explanation.
