I think that the type of bacteria used for a septic tank would have to be
one that is anaerobic and as such would digest the muck in the pond if the
muck were deep enough. It is a bad idea to have that much muck in a fish
pond, since the gasses given off are toxic to fish. I look at a number of
the bacteria on the market and some stink as they come out of the bottle,
indicating that they are sulfur fed anaerobic bacteria. I think they may
work in the corners of gravel filters, but shouldn't really have an
opportunity to work in a well oxygenated clean pond.

Recently I talked with several people who have started using Rid-X
septic tank treatment in their ponds to help digest the muck in the
bottom. They say it doesn't harm the fish or plants and is keeping
their ponds much cleaner.

Have any of you tried this? Is it really safe?
