In my 55 gallon, i have brown slime in the hang on back filter intake tube as well as it collects on my filter medium. I have taken it apart a few times and cleaned it all off only to have it come right back. This is the only tank I have it in, how do i get rid of it? I thought it was brown algea, but it is very slimey, so what is it? Thanks for any suggestions.
