Yep, Im glad this one wasnt concrete, Imagine heating a pool this size!!!!

Beema, what is a mineral pool?

Ours is salt, but the salt water goes back into a grid thing and is turned into natural chlorine, then pumped back to the pool, so I guess its 50/50. It also does some oxygen thing.. I dont know much about it, thats Ad's domain!!

I assume mineral would be better, and is it hard to convert??
