Direct Solar Pond Aerator/Venturi pump for oxygen and current design help

As the snow begins to disappear I am full of ideas for projects, but as always I have run into roadblocks due to my limited experience.  I have found several direct solar aerators online but I got reading that you can use a regular water pump and turn it into a venturi pump which will give you oxygen as well as a current.  My pond is 2 acres but only 6 feet deep.  I have a guy welding up a dredge to clean out half of it but I want to keep the weeds down and hopefully make it more prolific with fish. I need some help with figuring out what type of pump I need for this project or would it be a matter of a few of them? I am assuming a continuous use pump is ideal but I am lost with sizing.  Any help or direction to good resources are appreciated.

They seem really expensive for what they are.

The cheapest units I found were $3500.

I think you can accomplish this for far less money.

I wonder if 2 acres of pond is big enough to not need aerating. I don't know, but it seems to me natural ponds do ok without aeration.

If it fills from rain perhaps making the rainwater drop over an edge would be enough.

What I saw when I looked up the $3500 direct solar aerators looked liked serious overkill. Those are made to look cool, I doubt anything near that is required.

What are you dredging out, dirt or plants? And if plants,what kind?

I don't know, but I'm watching this to see if you get any good answers. I'm curious too.

Thanks for the input.  Pump prices I am seeing are in the 100's of dollar range not 1000's but you are probably thinking of the panels and other parts. I have that stuff lined up already cheap and cheerful.  As per what I am going to dredge out is just sediment and muck.  When I walk in the pond there is a couple of feet of just much from decomposed plant material. I think the muck has blocked the natural springs in the pond. If I get the springs opened up again I do not have to worry about the aerator.  The plants I am worried about are cattails.  They have really started to take off in the last few years and I do not want to loose the pond to them.

Cattails are edible :D
But amok ones might be too much...
Out competing them might help. A balanced ecosystem is always less long term work.
A search here came up with What do you grow in your pond?  and Minimizing muck/algae/etc. in a small pond?

:D
