We have filled our indoor in ground pool about 2 weeks ago. We are using the blue lagoon UV and Ioniser and want to avoid chemicals (chlorine). The pH is between 7.2 and 7.6, the alkalinity is good (around 120) and the copper content is now at about 0.6ppm. I have introduced a floculant twice and have vacuumed the remains from the pool. I think I need to start looking at shocking the water on a (semi) regular basis. I have been sold 2 products but looking at them now I am not sure what and if to use either? Fi-Clor Non Chlorine Shock (talks about bromine testing and not clear how long to leave before swimming again) and Fi-Clor Superfast Granules (stabiliser-free chlorine). Any help would be greatly appreciated as really lost on what chemical / non chemical treatments we should be using, and how often. PLEASE HELP
