I just read 2 threads on the forum about CYA levels, and I am not sure which one to follow. 1 thread in the SWG set up advice sticky states to keep the CYA level high...between 60-80 in order to help preserve the cell.
Another sticky about "what the measurements mean" states this:
If you are using an ORP controller, keep CYA below 50.
So...I am using the wonderful Autopilot total control systems, and I am not sure as to where to keep my CYA.
I also added Borax this year...and it seems to have made my water "sparkle" and really, really cut down on my acid consumption!
