Just wanted to thank everyone for the great info on here. We are a couple weeks away from signing, and have learned alot while reading this board. I was able to get alot of great ideas for our in ground pool in Tampa we will have built. So far looks like we are doing salt water, krystal krete finish, heat pump, and variable speed pump, led light. My only flip flop is the De filter or cartridge, when the wife heard it was a carcinogen and needed to be backwashed in the lawn she got very concerned since we have a dog and kids. Any thoughts ?
