Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Question is this wanted or not?

I would venture to say that the dye you have already applied is the partial cause for all the dead FA you now have. The reduced sunlight is causing it to die off. It will take some time, but it will eventually kill most of it off.

The important thing now is to try to remove as much of the floating mass as you can before it decays and sinks. If you let that happen, it's just going to add fuel for another bloom of a different kind. Algae, whether it be FA or planktonic will be the first to take advantage of the added nutrients. You need to make sure wherever you dump it, it doesnt get washed back into the pond.

PA lives in the top 3-4 feet of the water column and while dye will hender it from growing, it will not stop it completely.
