Pond Boss Forums MANAGING AN EXISTING POND Fertilization When to fertilize?

When should one fertilize a pond? We have huge amounts of life in our perch pond, FHM, Common shiners, Crayfish, and abundance of common local snails that are doing a number on the algae.

From new we have had about 12-18"s of visibility in the pond now this week it is gone to 3 feet. I do put in some aqua shade to keep the FA down and gives the pond a nice colour.

Kids swim in the pond all summer as well.

Should I be playing with some fertilizer or just let it be? Just noticed another hatch of very small minnows again too.

Any input would be greatly appreciated.

Cheers Don.

P.S. what numbers of NPK should we use if I should add some?
