STABILIZER/POOL CHLORINE USE
by D. LEE
WOULD PARTIAL SUNLIGHT CREATE THE NEED TO USE IT? WHICH CHLORINE, CALCIUM HYPOCLORATE OR SODIUM HYPOCHLORATE, WOULD BE BEST FOR AN INDOOR POOL? Thanks for your questions Cyanuric Acid (CYA) as you know is the stabilizer for the pool chlorine. Most of the time CYA is not used for indoor pools because they are in a controlled environment while outdoor pools are subject to the weather, heat and the sun, dirt, debris, animals, etc... Indoor pools can use CYA and there shouldn't be any harmful side effects. The YMCA pool where I'm the pool operator doesn't use CYA either. Really it comes down to two things: Financial Health of the pool You can try to use CYA in the indoor pool and it will probably increase the effectiveness of the chlorine, but it might be a wash financially. You'll use less chlorine but need to buy pool tablets for the CYA. On the other side, say you're only saving a few bucks in chlorine per month, but then you're adding another chemical (stabilizer) into the pool that it might not need it. I would try it for 2 months and see what the outcome is, both financially and for the pool. First month without CYA. Write down the dollar amount of chlorine used in that month and keep a record of the readings. The 2nd month try it with the CYA. You can use Dichlor to bring up the CYA, then Trichlor tabs to keep it there. If it's about the same, I'd go without using CYA. Partial sunlight might create a need for CYA, but I would ask how much chlorine do you go through now? For your 2nd question about chlorine, it depends on the hardness of the water. I'm in Albany, OR so the water here is very soft, about 2ppm. I don't know which part of OR you're in, but if the water is soft, I'd go with Calcium Hypochlorite. Calcium Hypochlorite..Swimming Pool Chlorine..Chlorine Granules It's safer, lighter, easier to store and apply. For hard water, maybe over 150ppm, go with liquid chlorine. Sodium Hypochlorite..Swimming Pool Chlorine..Water Care Also get a Taylor Reagent FAS-DPD K-2006 water test kit. Pool Water Testing Kit..Balance..Chemistry Hope this clears it up for you Best of luck Robert |
