Hello all! New homeowner and first time pool owner. Bought a house in Phoenix and pool had gone completely green while previous owner vacated the home before we purchased it. Pool was great for a few weeks after we had a green pool recovery completed by a pool company as part of our repair addendum. We first started testing the pool after seeing algae within a week and saw that our alkalinity was really high (240+ range) and thus our chlorine wasn't sticking around long. A month ago our pool went solid green, used Green to Clean and shock per Leslie's recommendations. It worked, pool came back great. A week later, solid green again. We used Green to Clean again, this time no luck. We had our sand filter changed out last Monday, did the Green to Clean again on Tuesday and now we're still green. Went to Leslie's again today (enrolled in their algae free guarantee program so at least we're getting free chemicals now) and tested our water (10,500 gallon pool):
Leslie's recommended draining our pool 1' at a time in the evenings (plaster pool, obviously can't drain in the summer) and filling up with the hose and the pool water line to fill quicker and lower our TDS. When we are shocking as part of Green to Clean we're seeing a bunch of shock floating on top of the water and not dissolving. We've been dumping money into this pool and can't use it, so I'm hoping there are some recommendations from this board. Thanks, all!
