Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Bottom of pond covered in coontail

Look and see what Water Primrose looks like.........

Too much plant life in the pond can create low O2 events at night. As the sun sets, the plants start using and not producing O2. O2 in a pond is typically lowest 30-45 minutes before sunrise.

Coontail can be partially controlled by Triploid Grass Carp, but the only problem with them is twofold. 1) You cannot tell them WHERE you want the coontail to be eaten. 2) 7-8+ years down the road when they are huge and slow down eating the underwater weeds, the only way to get them out of the pond is usually be electroshocking the pond, or by bowfishing them out.

And electrofishing isn't a 100% foolproof way. We electroshocked a customers pond every other year for the last 6 years and only shocked these two last year.



We had tried for a number of years to get underwater weeds established in the pond, and couldn't understand why we couldn't........ Here is another picture of the bigger one. It weighed 49# with the tail still on the ground. I couldn't pick it up any higher.



A mixture of Diquat and Cutrine Plus can be used to spot treat areas of coontail.
