It was OK. But only the CYA. The 4 in 1 CYA something something was not.Walmart here has Clorox brand stabilizer (CYA): $21/4 lb bag. I know most Clorox products are not highly regarded for good reason at TFP...same with stabilizer?
No matter if it's salt, cyanuric acid, or calcium chloride, make sure the bag says 100% and/or pure. Even if you bought it last time and checked it then. Manufacturers change things all the time and you'd rather know before you dump it in.
