Our pool was installed earlier this week and I am so happy to have found this site. I have been reading like mad (I think my head is about to explode), but I have a very basic (stupid?) question that I couldn't find anywhere: the instructions with my filter tell me to "superchlorinate using unstabilized granular or liquid chlorine before starting the filter". I thought the pump/filter should always be running whenever adding any chemicals (especially with a vinyl pool). Am I over thinking this? Just confused?
