I'm new to this. Set up a large above ground pool and I'm not sure where to start as far as chemicals go. 15,000 gallons, filled from our well over the past two weeks. what now? (sorry for my ignorance... )
Two decisions to make. How are you going to chlorinate it and how are you planning on testing it? I'd get a gallon of bleach in there pronto---at least 6%. You're at least gonna need some CYA to help protect it--available at Walmart. We'll need GOOD test results to advise further. Read up on the basics in Pool School here (button top left of page) and consider a TF100 test kit from TFTestkits.net.
