Pond Boss Forums GENERAL QUESTIONS Help Can you get deep mud out of pond bottom?

Installed my aeration system last week and noticed 12-18 inches of thick mud / muck on the bottom. Is there any way to get rid or to eliminate at least some of the mud in the bottom of a pond?

If this sediment has a significant organic component, the aeration system may well help reduce it's thickness over time.

Mechznical methods of getting it out are usually difficult and expensive.

Confused on "significant organic". What do you mean?

Is the mud/muck form leaves (organic) or washed in eroded soil (inorganic)? A mix is probably normally found.

As Theo mentioned aeration should help a bit with the organic stuff. You can accelerate sludge removal by a process called bio-augmentation or bio-manipulation in which you add beneficial microorganisms to the pond. Coupled with aeration, these critters will consume organics, reduce nutrients and therefore will even help reduce algae and improve water clarity. In my opinion, this should be a periodic activity in almost all long term, sustainable lake/ pond management plans.

WaterWizard, is there a natural occurance in which microorganisms thru bio-augmentation or bio-manipulation reduce sediment? If so, what conditions cause this?

You can think of a pond bottom like a septic tank. In fact, there is a thread about using septic chemicals to reduce pond sludge on this site. Anaerobic bacteria can decompose sludge, but are very inefficient at doing it. When you add aeration to the pond, aerobic bacteria as well as anaerobic bacteria are able to decompose the organic sludge. This makes the decomposition many times more efficient. Some people have even posted about adding One Flush to their ponds that have aeration and have had noticeable results.
