As far as I can tell, the previous owners of our house did not use CYA in the indoor pool at all. There was none in their pool chemicals, and I got my testing kit today and the test for it came back without any trace.
Should I be adding CYA, or just run with it as is and figure that's one less chemical to worry about? Resources I've seen online have suggested it's kind of optional... but which is optimal?
