I'm in Tidewater VA, and have a 2 acre pond, aerated 24/7. The water gets really clear in Spring and pond weed grows from 8 ft deep to surface. It appears the pond weed is getting cut off near the bottom and is floating in mats on the surface that make fishing impossible.
I put 4 triploid grass carp in 2 years ago, could that be what is cutting the pondweed off at the bottom?
The pond has a lot of willow around the edge, which makes raking very difficult. Is Diquat my only option to get it back under control?
