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

A client has a pond that color. 7/8 surface acre, average depth approximately 4 feet. I used 715# of Phosloc to treat the pond and the water looks a LOT better now. I can't tell you how long it will last tho. That amount was determined by SePro when they were given the information on the pond. Visibility in that pond always hovered between 10" in the summer and 18" in the winter. Very high nutrient loading.
George, I didn't suggest tilapia here because the algae is free floating. Tilapia can and do filter feed, but not well enough to make a reasonable impact on a situation like this. To help control free floating algae like this takes about a 150-200 pound per acre stocking rate.

Rex,I am strongly "editing" this post. Please accept my apology due to my misunderstanding of your "free floating algae" terminology. After closer examination of the photo, please allow me to "backtrack" on my statement. Scary looking "stuff" that deserves surface aeration - not tilapia.

It now has large surface aerator like Todd Overton's ponds, vertex twin aerator and f1000 fountain. We put in 25 lbs of adult tilapia back when water hit 69.
No fertilizer ever used. We have had a heavier rainfall than normal this year and cooler weather.
Here in the Midwest after our drought broke and rain came, the algae problems really exploded! I could only theorize that due to the very wide geographic coverage of unusual and heavy algae outbreaks where it had not been before, the decayed matter in watersheds, such as dead grasses that had succumb to the drought washed into the ponds and overloaded them with nutrient.
I suspect the recent rains in Texas and Oklahoma will cause the same situations.
