I bought baking soda at Costco 13.5lbs for $7, then off to walmart for borax 4lbs12oz @ $3.50 a box. Muriatic acid from home depot was $7 a gallon, is that a good deal? It was called safer muriatic acid from Kleen strip, is that the same stuff. The guy behind the paint counter said they weren't allow to sell regular muriatic acid in NY anymore. Can you buy CYA anywhere besides a pool supply store? They wanted $10 for a 4lbs bag, is that reasonable? Also my aqua rite manual says I need 12lbs for a 18K pool but, the bags say 3lbs for every 10K which works out to 5.4lbs. Which is right?
Thanks for all your help
