Bought a house with a 25k pool 2 years ago (going on our third summer with the pool). The pool has always had issues keeping FC levels above 0 and high phosphates. This year we decided to switch to salt with a pentair ichlor30 and have been keeping it at 60%. The water is 85, and the pump and ichlor run 24/7 no timer on the pump. The pool was crystal clear since the opening of the pool, but noticed what we thought was light staining on the bottom of the pool. The FC levels were not registering, checked the phosphates and they were extremely high. I treated the phosphates with 3 bottle of phosfree, checked and then one more bottle. Phosphates cleared up. Unfortunately that stain wasn’t a stain and apparently black algae. We super shocked the pool 8lbs of hypo chlorite, while treating with a black algae remover. The stain was gone almost instantly. The FC was still low the following day and were told to add 8 more lbs of chlorine…same result. Checked phosphates they were low. The algae stain also re-appeared. Next guess was chlorine lock. Was told to put in 25lbs of hypochlorite. The FC registered off the charts for 2.5 days. The afternoon of the 3rd day the FC went from 8 in the morning to almost 0. The cover was off all day and the CY was low at 38. I added I gallon of pool conditioner for the CY last night and put my ichlor on 100%. I also added 1/2 of PH up since my ph was around 7.0. Also the water isn’t clear anymore and there’re white granules in the pool filter (my guess is calcium from all the shock). Any help is appreciated! The pool has been opened since the end of May with the ichlor. I have dumped almost 50lbs of hypo and 9 gallons of liquid since the opening of the pool….extremely frustrated with not much solutions from the pool stores.
thanks!
