Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants To Much Cutrine Plus

IF there are no underwater plants in the pond, the phytoplankton and algae are the things that put O2 into the water. There's a reason for the booklet that is attached to the label, it tells the user how to figure out how much to use.....

It also depends on the amount of fish biomass in the pond.

While not Cutrine Plus, I had a customer use Copper Sulfate to kill algae. He ended up killing some of his Golden Shiners. Too much copper in an area did it.
