Hi all, Perhaps a dumb question, freshly plastered and just filled pool, will be salt pool in 30days, need SOME chlorine to keep water non algae growing as it used to have LOTS of problems before the rehab, want to get to, 1-4ppm, right now testing at .13. The start up steps say No Shock for 30 days BUT liquid chlorine to keep water good…..went to supply store and said NEW PLASTER concerns and they sold me liquid chlorine but on opening box its liquid SuperShock…..is the risk due to the % of chlorine in the solution!? Please tell me if I should return it for something else or if % is OK I might go ahead and use it!?.? ThanKs!
