Re: Is there a "correct" CYA?
ChemGeek knows his stuff!
In my non-technical world, I keep my CYA as low as I can. I base my CYA level on losing no more than 2ppm FC on a daily basis (maybe a tad more after a party in August...). If my daily FC loss was above 2 to 2-1/2, I would raise my CYA slowly and adjust all ideal ranges in proportion.
You don't mention how your testing is done. Phosphate reading makes me curious. I see you have a PF number...
