SWG and Ph balance

[waterbear]

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.

I have the Aqualogic ps-8 (same salt cell as aquarite) and I keep my CYA at around 80 (it's a bit low right now at 55 but I am gonna wait until it goes close to 40 OR my builder fixes the leak in my skimmer before I bring it back up) and I keep my FC in my pool at 3 ppm and in my spa at about 4-5 ppm and I have had no problems so far.
Also, I wonder if the fact that the water in the cell is constantly being 'shocked' when the cell is operating vs. manually adding chlorine and shocking might cause a difference in how the pool reacts to the CYA and FC levels. That would be an intersting piece of research!

I agree; there was talk on the "old" forum about the steadier flow of cl keeping the water chemistry more stable. Thanks.

Already been done. The answer is yes. Prior to installing my SWC, I used bleach and always had about 0.5 CC. After installing the SWC, my CC dropped to 0 and has been there ever since. Sean has also mentioned in the past that the concentration of Cl is high enough that it does act like a continual "shocking" process. I can definitely confirm the results, as I have not had to shock the pool since I installed the SWC.
