Good morning all!
I am in my first season with BBB and going on my 7th week. Early on I felt I was having a high FC usage. I still feel I do but don't see or find any bad results. Pool is in direct sun all day. I do not use a solar cover. My latest results,
I get levels up to 7.5 to 8 ppm at night and by the next evening I am between 3 and 4 with loses of 4 to 5 a day. With OCLT test there has never been more the 1 ppm drop. My FC was a bit lower at 2.5 last night as I had ran a bit short on bleach the night before. I still estimate approximately 4 ppm drop. Does this seem normal? I had shown levels of 50 ppm CYA about a month ago and I had added a bit more stabilizer thinking that would help as I had average loses of about 4 to 5 then. Pool is crystal clear and sparkling. There has been very little bather load and most most days none. I just want to make sure that I am not missing something. Last night while in the pool I noticed several (8 to 12) waterbugs and can't say which type for certain and it just has me wondering. The sides and bottom are not slick or slimy. Thanks for any help or re assurance you can provide. Going thru 1/2 gallon bleach a day and it is more then what I had anticpated but if it is what it is I am loving my clear pool!!!
One more thing PH has hld entire time at 7.5 however most recent test on TA was 20 lower then last. Thought this may mean something.
