Newbie to the forum. We have a large pond that is hourglass shaped and half is deep the other half shallow. Lots of much and coontail and now duck weed and watermeal. I plan on buying an aeration pump for a 4 acre 20’ deep pond. That will break the bank. Then there is hoses and diffusers to consider. I like DIY projects, any suggestions on making diffusers and how many lines and diffusers I should use? We used to swim and fish in the pond and last year most of the fish died and we couldn’t get control of the floating weeds. Trying to keep my pond from becoming g a bog while trying to not break the bank. Any suggestions are welcome! Thanks in advance!
