Welcome to TFP!
Since we have seen a lot of very saddening posts about this lately, I have to ask: did you carefully level the area? Quite a few people have joined looking for help after filling and finding the pool is far too off-level. They have had to drain, tear it down, re-level, put it back up and refill. So please make doubly sure you level, and make sure you do it by digging down the high spots, not filling in the low spots.
