I just wanted to check in and say a big thank you to everyone....we have been in the pool virtually everyday for the better part of the last two weeks. The water is wonderful. I only infrequently add bleach and have added borax only once (my fault of course, for not getting her stabilized).

I keep telling my son, "best birthday ever!"...his request for a pool with a ladder has won us all a summer of fun. I now the experts understand (thanks again)....but for all you newbies out there....this is a lot cheaper and easier than I could have ever imagined thanks to the recommendations here.
