We have a thick gross green pond with the fish we catch are getting lighter in color. Have treated with Cutrine plus many times over the last two months. Also pond clear which is special alum product. Nothing works. We have twin vertex aerators and starting turning the fountain on the last few days. Do I need to get a large aerator like Todd at Overton's uses?
I know the feeling - We don't and won't use chemicals.
I am surprised you don't mention tilapia for algae control?
I would ask Todd about his aerator..
He solved our problem with Kasco surface aerator in addition to bottom diffuser system. Bottom diffuser in day time and surface aerator system at night.
Pond is naturally turbid due to clay soils but some turbidity is beneficial in my opinion.
Good luck!
George
