My CYA according to a water test at a pool store was 30; so I added to gallons of liquid CYA. This was because I was out of Reagent. The pool calculator said I needed about 180oz. I added 2 gallons. I bought some blue devil reagent off of Amazon. When I tested I got 30 again. Are there different strengths of reagent?
