I am still unable to pass OCLT despite running for 3 weeks now. My intention is to SLAM and then super chlorinate for mustard algae. I had a really bad bloom I could not get on top of for a long time. I have been through about 24 gallons of chlorine to this point. I'll post some more detailed numbers tomorrow as I have just added chems but is there any other possible cause of CL drop apart from organics or sunlight? Is there another option I could consider to rid myself of organics?
