I am screened in, but pool is on south side of house so very limited shade.Is this pool in a screened enclosure like many pools in Florida? If so, please realize that the screening reduces sun exposure by about 50%. Also, a typical screened pool in Florida is very close to the house so the house often shades the pool for a significant part of the day, further reducing sun exposure. I've found that CYA values as low as 40 or so work fine in that situation and chlorine consumption is still minimal, in my case about 36 ounces of 10% liquid chlorine a day in the worst part of the summer. I've now converted to SWG and with CYA 40 I can run my RJ30 at 40-45% for only 8 hours a day and keep my FC in the 4.5-6.5 range. That seems to be a sweet spot for this pool. My acid consumption is rather low as well, partially as a result of my TA being kept on the low end.
Currently I pushed my cell down to 50% and am doing about 10 hours a day and am holding at around 5.5 to 6.5 ppm FC right now.
The manual for the swg also says 60 to 80 cya.. so I am going to work up to that range.
I will keep testing, but I am thinking that if I can bring the hours a day down to 8 (roughly 2 full cycles of pool a day) and then drop the cell usage down.. I am hoping that this will cause my cell to last a lot longer too (pool guy had next to no cya and cell running at 100% and we still had algie problems and were burning through cells every 3 years).
So far a few weeks in my pool is crystal clear and never looked better and I am really appreciative of the help and advise of everyone here.
