okay, i'm beginning to comprehend...I will order the test kit tonight.

Meanwhile, since I would imagine that my CYA level is really low, should I go ahead and shock my pool with dichlor powder? And if so, what's the best way to add it--broadcasting all around the pool? Pre-dissolving in water? I have suncoast fast-dissolving shock, 99% sodium dichloro-s-Triazinetrione Dihydrate.

Thanks!
