After topping off the pool (we had closed it for the winter) and some spring rains, my CYA level has dropped to 10 ppm or less.
I have a leftover bucket of HTH trichlor tabs from the previous owner.
Does anyone have an approximation of how much CYA is added over time by the tabs?
I'm thinking I could just use the tabs until my CYA gets back up to 40-50 before going back to BBB. Being cheap , I'd also like to save on the CYA test reagent by not testing more frequently than I need to.
If this is a stupid idea and I'd be better served by buying some stabilizer at the pool store, feel free to tell me so.
