Thanks Michael --
Needing to keep the pH down is just the trouble I'm talking about. So, if I maintained lower FC levels, the cell would produce less chlorine, and thus less "caustic", and the pH drifting up would be minimized???

Has anyone followed Aquarite's recommendation of 80 CYA and FC of 1-3ppm? I'd sure like to hear how that has worked out! I thought there used to be an Aquarite sales rep on the forum. Might he still be around?

Thanks again.
