:? In my 3rd day of a first ever SLAM, my water has been clear the entire time, however I had green crud growing on the bottom and cove. Since the first brushing there has been no sign of green, CL level has been kept at 30+, I also have brushed at least twice a day. Today decided to shut down the filter for 1 hour to disassemble and clean, OMG split pea soup oozed out. Filter is now back running with new DE. Could the crud in the filter be causing my OCLT to fail, dropped 8 ppm last night :?:
