I live in the Northeast so my pool is not subjected to the high temperatures and scorching sun that others experience. I have a Pool Pilot SWG that maintains a 2.0 ppm FC while the CYA is 0. (ph = 7.5 ALK = 80 Water Temp = 80). It really does not fluctuate that much. I've tested it in the morning, afternoon and evening.

Pool Pilot recommends a CYA of 60-80. According to Ben's best guess chart this would require about 7-8 ppm of FC.

Here's my question:

If I raise the CYA to 60-80, will I have to raise the power setting on the Pool Pilot to achieve 7-8 ppm? Right now it's operating at 60% @ Power Level 2. As I understand, the higher the power setting, the shorter the life of the cell.

-OR-

Will the increased CYA allow the Pool Pilot to achieve those numbers without a significant power increase?

I guess I'm a little gun shy when it comes to adding CYA since it can only be lowered by draining the pool. I also like the fact that the SWG is at 60%,which is in the range of what the manufacture recommends.
