sacrilege I know but...
here in Austin the daytime temperature is getting to mid-nineties every day and I'm adding a lot of bleach - 3/4 of a gallon a day. This is going to cost me about $85 to maintain target fc of 5ppm. The water looks perfect, there is no CC and no overnight fc loss so I know it's not a secret algae lurking somewhere.
pool volume 26000 gallons
cya is 45ppm.
FC 6 ppm
water temperature 88F
pH 7.5 (this keeps going up and I now add MA 2 x week when pH gets to 7.8)
I'm going through about 2-3 ppm a day even if nobody goes in the water. If I add some cya or use trichlor tabs will this slow down fc loss? Maybe use some Is it time for me to add borates - which I've never done?
