I'm opening the pool after a year off and not using it. What do I need to do to get this back in order and ready for the kids to swim? Where do I start and what should I dump in it. Thank you for all your help.
Need to test the salt to get some idea where you are first. What does the SWG say it is?
Why is FC at 1, is algae consuming it faster than you can add it? That is algae level. Even when not slamming it should always be 3-5 ppm with CYA at 20. Chlorine CYA Chart
So are you SLAMing? A filter will not eliminate algae.
