Welcome to our forum.
Vinny,My Nature2 booklet that came with my cartridge states to shock with 1.5 TBS of dichlor for every 250 gallons, upon installation to activate the catridge.
Although I do have a closed mind, I try to become "enlightened" just in case there really is something to it.Too may people swear by this stuff even though I think it is a bunch of BS. Of course, people swear to magnet therapy and well I won't go there! Quite honestly, everyone quotes Vermonter and yes I do too. But he uses ozone , N2 and a healthy dose of dichlor with a dichlor shock ... get rid of N2 and ozone he still is treating his tub chemically not trying to skimp on chlorine.Maybe when I tried it the last time I was too new to hot water care to really appreciate or use it correctly. That's why I'm trying. The same will be with ozone. My ozonator puts out very little, actually all Dell ozonators put out very little. If adding a better unit maintains better water clarity for a longer period, then I'll be happy. But that's next years experiment.I will try to keep you guys posted as things pro and con happen.
