Two pictures of my same pond without FA and never a chemical in it, but managed two different ways. The first picture is about 12 years ago with no FA, but with the much needed green bloom, which you need for the food chain and oxygen. The nitrates from the fish produced the green bloom enough that I didn't have to fertilize. The green bloom also helps limit sunlight for weed control. My algae eaters for one acre were 20 KOI, 6 Israeli, and Channel Catfish along with 18 grass carp (too Many) for weed control. The algae eaters produced babies for the predicators to grow fat on. The other stocked fish were bass & bluegill. This pond is very fishable.
This second picture is now. FA is controlled with water plants mostly and tadpoles. The water has no green bloom but is very clear down to 6 feet. I am still experimenting with this pond.
