Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Help! Some kind of floating slime is taking over.

Jason, you might want to put Louisiana as your location. Having a correct location in your profile will help people give you the correct advice for your location. I doubt that someone can find your pond/property from telling us what state you live in.

Also, pond advice is regional. What works up here in the Northern part of the USA might not work down South where you're at.

Like was said, that's a type of algae. It is growing in the pond because of excess nutrients that aren't being used. Check into whether stocking Tilapia in the pond is legal in your state. They feed on algae, and will help you with the problem. Yes, Cutrine Plus will kill the algae, but as it decomposes, it puts nutrients back into the water, and the cycle starts all over again.

I'd stay away from the Yellow Iris. It spreads pretty quickly. When searching for plants near the pond or in the pond, ones that grow slowly are easier to control and cause less proglems long term. Blue Flag Iris works well.
