Does anyone have experience with this product? I have been having a bout with brown/red slime all over everything, and I can't seem to get rid of it. I have done complete tank scrubbs followed by water changes with no luck. This is a 20 gallon setup with a 96 watt T5 light, and 2 Koralia nano 450's. All the parameters seem to be in check aside from phos as I don't have a test kit for this, but I do run GFO, and carbon. The tank has been up for about 6 months now with about the last month and a half battling this slime. I have read other threads saying chemiclean gets rid of this stuff, but wanted club members opinions.
