Chlorine tab question

[Mariza]

So question then...how long does it take the tabs to build up
unacceptable CYA levels? I currently have a pool with probably
only trace amounts of CYA. I bought a tub of the 3inch tabs before I
found this site and read up on the BBB method.

I think my pool is around 22000 gallons, plaster IG. We switched from
Bacquacil to Chlorine about 3 weeks ago. I just finished cleaning out the algae /leaves and haven't managed to get the chlorine to my proper levels yet. I started on liquid bleach (6%) and haven't used tabs at all yet.

It depends on your starting CYA level, how fast you have the floater set to erode, and what levels you consider unacceptable. MOst people like to shoot for the 20-40 range. Others run theirs higher. It all depends on how much chlorine loss you have on average, and how diligent you are about daily chlorine additions. The tabs will continually drive your pH down, so if you're already having low pH problems, I would skip the tabs and stay with bleach.
