Ok so I've read the TFP method and pool school. I've got a couple quick questions. First, I read all about how bleach/chlorine/sodium chlorite is the best to use for shocking and for adding chlorine because it doesn't add anything else to the water
besides chlorine. I understand that part of things but I've looked everywhere in Albuquerque NM and I can't find anyone that sells it at pool supply stores or chemical supply places. I can buy pool stuff wholesale and I checked with the wholesale guys
and retail places like leslies and I can't find it anywhere. I was trying to buy the higher percentage but it looks like store bleach is what I'm going to have to use. My question is I checked home depot and they sell the Clorox stuff but the msds sheet says the concentration is 5-10%. Does anyone know what the actual concentration so I can enter it into the pool calculator? The home depot brand stuff is cheaper and on the MSDS sheet it says 8.5%. Anybody have experience with both? Also, I added stabilizer today because leslies said I had 0. Second question is how long should I wait to test my CYA level before I Slam shock my pool? I need to know my CYA level before so I know how much chlorine to add Correct? All help and comments will be appreciated.
My pool is 18k gallons salt system plaster using a sand filter
