Pool looks pretty good, considering we just got back from a week vacation and the 90+ degree weather. However, looked slightly cloudy yesterday and added a bunch of chlorine last night (didn't test anything, too tired!). Did test this evening though:
CYA=20-30? This test still gets me!
I plugged all this in to pool math, but I'm not sure what to add when. Can someone simplify and decipher, telling me what to do to get things balanced?
