Bought chemiclean today waiting to put it in until I get some more Rodi ready. Anyboday have any negatives about this stuff? I cleaned out as much of red hair and cyano that I could by hand and with a 10 gal WC. seriously like 2 lbs of slime it was gross it was gross. Any input would be great I know I need to do a 20% WC in 48 hrs and protein skimmer will probably go crazy(will be shut off with all filtrationduring the 48). Anything I am missing ?
