Foam Under Vinyl Liner

Hi, I've read/learned a lot on your website. I'm putting up a 24'x52" round AG pool. I'm planning on getting the dirt level as possible then using an inch or so of sand to get it leveled the rest of the way, then foam on that. I'm using preformed cove, and 1/2 foam board on the walls.
In my research most people say to use 2" foam for a base. But you recommend 1 - 1 1/2". You seem to know a lot about it, so I was wondering, is there any advantage to using 2" over 1 1/2" or even 1"? Or is 2" just a waste of money?
Couple more things too,
What’s the best solar cover in your experience? (I'm looking at the clear bubble 12mil one)
And, what’s your take on the HAYWARD/GOLDLINE AUQATROL RJ chlorine generators?

Sorry for so many questions, most places you ask you never know if you’re talking to a pro or a 12 year old! I know I can trust you. THANKS!!



Hi Andy. Thanks for the kind words and I am glad you have found some useful information here. There is nothing at all wrong with using 2” foam. You will loose another ½” of water depth and it is more expensive. Those are basically the reasons I recommend the thinner sheets. They all do the same job and make a very nice pool base.

This is the cover I have and am very happy with it. Solar Pool Cover There are many brands and styles to choose from and I have used several without noticing any major differences worth taking note of. The thicker 12 mil is good and a warranty is nice also.

I have never used a chlorine generator and have only installed a few. They are just becoming popular with mixed reviews from what I have read. Some people quit using them and go back to using a floating chlorinator and others swear by them and would never use anything else. I would have to personally know someone who is using the unit, and loves it, before I would buy it. As you can see, Chlorine Generators, there are a lot of models to choose from. I’m sure the time will come when I will have one on my pool, but till then I’m not much help.
