Been using BBB method following this forum since 2015. Always have great success opening pool even without having a good cover. Ours has some holes and Dog likes to run across it like it’s not there so haven’t used it for 3 years. I do blow out lines and put all equipment in shed for the winter so everything is functioning properly. This year has been different. Removed 9 garbage bags of leaves and vacuumed several times so as confident as I can be that all is removed. I Can only see about a foot down after 14 days of slamming the pool. That is the problem.
Adjusted TA to 100 and PH to 7.4 as always. Raised CYA and let it settle for a few days to 30 ppm then raised to 50. My normal setting. Tested everything with Taylor k-2006 kit. Triple checked CYA at 2 additional pool stores to confirm 50ppm. Then I started adding 8% liquid chlorine from local hardware store that I have been using for several years now. They say it’s 12% but based on size of pool and increase per gallon added I believe it’s more like 8%. At 17$ per five it’s still the best deal around. Kept free chlorine at suggested levels for each cya level testing 2-3 times a day. About 4 days ago I noticed that the FC levels weren’t dropping despite the pool still being cloudy with visibility about a foot. So I checked combined chlorine and it was 2.5ppm. At This point I was slamming at 20ppm. I looked up on The inter webs and discover something called chlorine lock. So I raised FC to 10x CC folllowing the generally accepted breakpoint rule. I let sit overnight and this am there was no change in clarity at all. Just a lot more foam on the water surface.
Any advice would be greatly appreciated as I am stuck and really don’t want to waste water by lowering and refilling until I have tried everything . Should I try a non chlorine oxidizer? Read mixed things about those and their effect on CC.
