Also wanted to add: re: sticky water My first thought was maybe salt, but our Pool Pilot says the salt level is 3600 ppm and the HTH salt test strips pretty much agree (3680)....but not sure of the accuracy of either. It's not horrible sticky, but just as it dries, my fingers feel sticky for a bit. Then it goes away. Maybe it's been so long since the pool has been open that I forgot what the saltwater feels like? LOL Just don't know what else it could be.
