After testing my pool this morning, Im showing no yellow at all in the test kit. So I dumpted a gallon of shock in like I always do, but its still low. I went to Home Depo and they had no liqued shock but had one pound pacages of Pool Time Shock Xtra Blue 6 in 1. My Pool is above ground 30 X 15 and was going to dump two in. what do you think?
I never used powder before always liqued.
