Re: New Pool Owner - Chlorine not holding
I have a pool that ends a season with around 50 ppm CYA and starts the next season with 0 ppm. Ben, how does a pool owner know which of the three situations you described above the pool comes under: nitrogen gas, nitrates, or ammonia? If the CYA was converted to ammonia, would there be a smell?
I start each season by adding enough CYA to get to 20 ppm (calculated, since I can't measure that low), add liquid chlorine to 10 ppm, and then run the trichlor chlorinator for a while, usually until it gets hot toward the end of May. Then I switch to just LC. My starting water has always been clear despite a fair amount of organic debris that blew in over winter.
Given my personal experience, is it valid to say the CYA in my pool is NOT converted to ammonia? Or to nitrates, because I don't have a problem maintaining chlorine? That would then be the 'test' , wouldn't it, whether the pool holds chlorine at startup?
