Filter for 120,000 gallon Pond

Wow, big project there. Your gonna need a lot of fx5 s lol. There are special filters that the government installs in disgusting overcrowded and toxic lakes that help to clean it up via biofiltration. I have no idea how you would find one though.

just an idea...

get a big plastic water tank (not too big but not a little midget one) fill it with media and those big filter wool pads. drill to connect 2 pumps into it, have one running from the pond to the roof of the water tank and another running from the base of the tank back to the pond could add a uv also not sure how well that would work but? sounds a like a cheap easy option in my head would work well too, cleaning might be a bit of a pain..

Just an idea the only actually filter that comes to mind are the big pool ones some people use over here but they have to be indoors i believe?

3 or 4 high school kids with shovels? Shovel the muck into some sort of perforated containers so the water will drain out. Then till the muck into your vegetable garden.

It really sounds like you need more of a dredging operation before you start thinking about a filter. A good mechanical filter might help clear the water while you are dredging the muck.

Aquarium folks, like you and me, know that a turnover rate of 5 times per hour is fairly standard and typical. In a pond, that kind of turn over would require huge pumps and tons of electricity. A turn over of once per hour is probably do-able but would still require quite a large pump or several. It looks to me that this pond is doing fine on its own. Many people strive for years to achieve a pond that looks and behaves as a natural body of water. Dredging and removing plant matter may upset the balance this pond looks to have achieved. A UV sterilizer and a good vacuuming is all I would do if this were my pond. Maybe some sort of circulation or aeration but in the words of whoever said it,"if it ain't broke, don't break it!"

When I talked to our fish farm that raises native fish here they said wait until the coolest part of the year and muck it out with a track hoe. If you do it when it is the coolest time you will lose the least amount of fish. You need to add new fish to farm ponds every so often just to keep them from being inbred too much. At least that is what they told me. We have a three acre lake on our property that needs to have this done also.

It does have aeration there is well for the pond and the well leads to a fountain in the middle but there is no circulation in the bottom. My plan so far is fix my well, add a grass carp, add some trap door snails, and add some muck away and pond clear chemicals.
