next question-UNDER liner? What did you use?

[kimkats000]

I have ordered the pool! It should be here by Wed. of this week. SCARY but SO excited!

So what did you use under your pool liner (over the sand that is)?

Has anyone used poly styrene? It is insulation I can get from Lowes. It seems that it would work and be much cheaper.

With my newest pool installation, my installer used the Happy Bottom foam. Under my previous pool, my installer (different guy) used a pink foam from Home Depot but I can't remember what it was called. It wasn't specifically made for pool installations but had some other purpose. It worked fine. I'm sure it was cheaper than the Happy Bottom foam.
