Ok, I knew it was coming, I have shallow 4:1 slopes, and now I'm having major cattail issues & algae problems.

What I don't get is, the ponds are connected via a 12" culvert pipe, the large pond has a ton of weeds, and green stringy algae under the surface, and a lot of floating green/brown bubbling algae, and cattails, the small pond has virtually nothing. Not sure why they are so different.

The large pond seems to accumulate a heck of a lot of decaying plant matter, the small pond none.

What is the solution here?

I can't imagine a windmill aeration system alone is going to be a panacea?

If I do start to aerate, how long will it take? Before I buy a windmill, I wanted to try a couple bottom diffusers (12ft deep) and a small diesel engine with an air pump. I have no power near these ponds.

If I run the aeration for a week or two, is that going to make a difference?
