I have a 125 gallon FOLWR with a large lion, huma huma, grouper, niger and toad fish. I seem to grow a red slime on the rocks and the gravel. Every couple of weeks I clean it off the rocks and scrape up as much as I can off the sand. I have treated with red slime remover and chemi pure multiple times... but it doesn't go away. Any suggestions?
