We use bromine tablets, three in the skimmer door basket at all times. The dealer recommended tossing in a table measuring device amount of a chlorine product, dichlor? not certain,..... the dealer set me on to it.....after each soak for good measure I guess, and I do add this but usually every second time. Two soakers, three maybe four times a week. Started up first week of August, same water now. All is well, levels are fine, water is still clear. A few times the water did get cloudy, but I seem to have to flush out the filter every week to 10 days. A little robarb blue stuff and two filter cycles later all is back to crystal. Maybe I am lucky?
