I have a ozonator that is 200 mg hr I have 115 gallon system Right now I have it running through my asm skimmer. I However do not have a orp probe or controller. So I set it at 25% does anyone know where I should set it untill I can afford a controller and probe. I do not whant to crash my tank and i know it is a shot in the dark.
Also If anyone has one for sale I might be interested thanks Frank
