Pond Boss Forums MANAGING AN EXISTING POND Fertilization Plankton Bloom Started, Now Foam?

I was not trying to be condescending - just trying to explain how complex aquatic systems can be for someone to try and keep them looking like pristine waters. Quite a difficult task which I assume is why the small management firm is no longer doing the management - poor results. No need to be sorry that you are not an expert, there are very few if any experts when it comes to properly managing Mother Natures waters. They are very complex interactive ecosystems. I still think you will need some luck to get that problem cleared up. Sorry you did not like my advice. There very few easy simple answers to problems similar to those of your BOW. Maybe someone else can provide some easy answers. Decomposing stuff is probably all the algae and weeds lying on the bottom that were killed a couple weeks ago. It takes time for a lot of that coarser material to decompose.
