I am about to have the big one. Just got back from local pool store having my water tested. They tell me that my CYA level is back to 135! Impossible I say since I have totally stopped using any stabilized chlorine products. Maybe, if I have been brushing my pool there was CYA on my pool walls which is now in the water- was the reply I got.
Please tell me this makes sense. I love my pool- my idea of heaven is a good book, a cold drink and my pool. But this summer has been a nighmare trying to lower my CYA levels. I would never have known it was elevated if I had not bought a container of test strips for the first time. No one has ever told me to test my stabilizer levels. I tested for choline and free chlorine, ph, alk.... and if I took water to my pool installer then he tested it including hardness.... but again no one mentioned CYA!!! So imagine my horror when a new pool place tested it and told me my level was 160 ( this morning she told me it could have been higher but that is the limit that they test)
Since I have a fiberglas pool and the installer told me not to lower it more than 12-15 inches at a time, emptying has not been an option. I have done a partial empty 5 times. Oh well, I quess I will now do at least 2 more before I have my water tested again. I have Ben's kit on order so I have to rely on the store. I used a Walmart HTH kit but have run out of CYA reagent.
Until I get my CYA level down all I can do is keeping adding Bleach (3qts at least a day) to maintain some FC so that we can swim. (I have not been able to get the cl level above 10 and of course it immeadiately begins dropping) Any other suggestions?
