Pond Boss Forums GENERAL QUESTIONS Water chemistry 1 acre 4’ deep pond in middle GA with Alkalinity 0

Coverage is what amount covers the bottom of the pond. Personally even though we sell fish, a more accurate control would be using herbicides. You can't tell the TGC where to eat the plants and fish like the edges of weed beds.........

Bill Cody Note - You could consider using the appropriate herbicide for some spot or zone treatments to get it significantly reduced and then add some TGC for longer term hydrilla control. IMO you want some hydrilla or other submerged plants to be present to compete with filamentous algae (FA) growth. FA grows primarily when no other plants are using the available nutrients. When a pond has enough submerged plants to use the available nutrients, there will be no FA problems. FA lives when there is an excess of unused dissolved nutrients.
