Experience has taught me that enough algae over the winter will eat through the chlorine and then consume the CYA as well. I tested with the water at 70 degrees and got no result which doesn't really surprise me. I'm figuring at best it's 20 or lower.
I'd just as soon get this leveled first before bringing up the CYA. Any reason why I shouldn't? And should I just make sure I'm over the Shock number of 10 in the chart?
