Overstabilization?

[Watermom]

Crazimom - You say that your numbers are good. The only actual number you posted was your cya. I would suggest posting all your numbers. I'm especially interested in seeing what your calcium hardness reading is since you are using cal-hypo. As far as using the bleach, give it a try. It can't get any easier than opening a bottle of bleach and slowly pouring it into the skimmer. As the others have already said, your cya is already at the upper end of acceptable at 60. I actually don't like mine to be that high. Using pucks, it is going to continue to rise. You don't want that. Post some numbers for us to look at and give the bleach a try. I don't think you'll be sorry.

Yes - using tabs will over stabilize (Raise CYA) and raise your ALK and Cal Hypo will raise your Calcium level. The only way to reduce these # is to drain and refill.

Within a year of of getting a pool - I had CYA >200 and continual algae problems. I was skeptical at first about bleach -- but found this forum - I switch to bleach and kept it in control using the adjusted chart for higher Cl. This worked -- but was difficult to maintain the high CL -- I drained and refilled to get the CYA down -- (it's was alot cheaper) -- now I use some bleach at that's about all I have to do.

Bleach is my choice -- but when I can budget the convience - I'll switch to salt.
