Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Copper sulphate

Using a Chelated Copper algaecide is better than using Copper Sulphate. It will stay active in the water longer than Copper Sulphate.

The treatment schedule is because when the algae dies and decomposes, it uses oxygen. There's a possibility of causing too much of an O2 drop in the pond if you were to treat the whole pond at one time, depending on the amount of algae that is killed.

There's a pond in Lemont that I visit twice a month, that has a waterfall and stream that is actually water pumped from the pond. The owner likes to have trout stocked in the Fall for the winter so I treat the stream about every 6 weeks with Phycomycin. I would use a copper based product, but can't because of the trout. The pond has a very good bloom in it during the summer so algae rarely grows to an extent that it would be a problem.

Sounds like the Nate did a heck of a job on the pond!
