+1 ... I am under the impression that tumbling carbon erodes it which releases carbon dust into the tank. I have read some primary literature that showed the carbon dust can cause a disease in some species of fish. I have always fixed my carbon in place (ie inside a bag or between sponges) and fluidized my GFO at a light tumble.

So what I've read, and been told, about using 1 cup of carbon in a TLF 150 for my 110g total system is not the best idea ...
I see the point where there will be no concern about carbon break-down and subsequent HLLE, or other issues, with a full reactor

Guess I'll be filling my reactor to the top from now on
