My question: If I need to shock when opening my pool AND I need to raise my CH level, would I be better off to use the store "shock" products? Cal-Hypo would do both, wouldnt it? Or would it not be fast enough? My opening CH level was 200 and I know it has to be at least 250. Started with 0 chlorine also.
Full set of numbers:
Just wondering, have to make a trip to WalMart anyway! Thanks!
