Actually I just redid the 20g Long as my 1980 tank developed a leak. Unlike the process above I could not prevent "stiring" up the peat moss and the tank was a very dark brown mess at first. That was the peat moss. But in three days the peat moss settled down and now I have a nice dark substrate. I also have a feeling that any circulation or filter would just keep stirring up the peat moss.
