low cya

[gettinthesplash]

I have a 24' above ground pool. My cya is too low to be measured with my Taylor test kit. And I have a feeling my chlorine is disappearing too fast. I use liquid bleach (12%). I test chlorine levels at least every other morning, a lot of times every morning, and I normally get .5 ppm or 0. Then I add at least a quart. I have some chlorinating granules. Wondering if I can use that for a little to bring the cya up or do I just need to go get some stabilizer? These are the ingredients: trichloro-s-triazinatrione 71.8%, boron sodium oxide pentahydrate 8%, other (clarifier/filtration enhancer/sunlight protector) 20% I have not had any problems with algae this year, and I don't want to start.

[Admin note: trichloro-s-triazinatrione = trichlor; boron sodium oxide pentahydrate = borax or "5 mol borax". The odd name is used to try to keep people from thinking, "Oh, that's just borax!". ]
