(Aldergrove, B.C Canada)
I just bought a used 21' x 54" round above ground pool which is in great shape. The instructions tell me to dig a sloping basin 6" to 8" deep in the middle. Do I need to do this or can I make the bottom just flat?
I also just bought my liner and Rhino floor pad through Pool Supplies Canada and I'm concerned the floor pad won't fit properly as it says it's flat?? Any information will be helpful, thanks!!
I have never seen a set of instructions that called for a 6" deep area. That would lead me to believe they were using a special liner, one made just for that pool.
Since you bought your liner from a different company my guess is it's a standard flat bottom liner. In that case, yes, leave the bottom flat. The pad will fit much better that way and the liner probably will also.
