I'm trying to get a grip on the CYA level in my pool and I'm getting a little frustrated because I don't trust the results I'm getting. I have two different test kits: TF100 and the cheap HTH 6-way test strips that I bought while waiting for the TF100.
How accurate is the CYA test on the test strips? To my eye they read much higher than the presumably more accurate Taylor test.
My pool water is crystal clear, so I really don't have a problem. It's just that I would like to use the least amount of bleach that I can safely use, but how can I determine this without having an accurate CYA measurement?
