word. I wasn't to worried about the alkalinity. I just want to get the cya up, so I can hold the chlorine. I'll recheck in a couple days and see where its at. I need to do a thorough vacumming of the pool it is loaded with deceased algae. Dang if I was thinking about it i would have done that before I put the CYA in. Oh well live and learn I'll post back results ina couple days. thanks for the help.
