Hi, Well I thought I dodged the red slime bullet in cycling my 210, but I walked into my office this morning to find red slime in the sand. I think I cursed myself when I joked about adding 100 snails and crabs the other day. So, the cleanup crew is on order and I've cranked up the skimmer, but I was wondering if anyone has any experience in using PP to help reduce dissolved organic compounds? Opinions? Cautions? Oh, to head off the normal algae question... I'll check it again tomorrow, but my phosphates were low (I need to check my log, but it was less than .02 ish from memory) 2 weeks ago when I last tested it. The test kit is at home. Thanks!
