So today I had some free time and was looking at my pool when I got to thinking (its dangerous, I know)
Chlorine I can buy anywhere Bleach is sold. To change my pH I can buy washing soda and/or borax wherever I buy laundry detergent or Muriatic Acid at the Hardware store. To change my TA I use baking soda, and get that at multiple places, a grocery store, target, walmart, etc
since my pool is vinyl I don't really worry about calcium chloride and where to buy it, but then I get to CYA, the Cyanuric Acid. Not exactly sure where one buys thats other than the pool department of walmart or at the local pool store. Besides "Stabilizer or conditioner" what else would I look for when making this purchase, trying to keep costs down yet still be effective? Where does one buy Cyanuric Acid, hardware store, pool store, discount department store like walmart?
