Hi all. First time posting on here was hoping I could get some help with my pond. I recently purchased a property in northern New Jersey which came with a quarter acre pond which is about eight feet deep on one side and it then becomes about two foot deep on the other. Last year I battled the duckweed and put grass carp in at the end of the summer with not much luck. This year I added more grass carp and a air pro rocking piston aerator 1/4 hp with two diffusers that Iím running about 12 hours every night. However this year the duckweed is again coming back strong as well as some green floating algae. The other problem that Iím facing is my neighbors septic field is above the small stream that flows into my pond which Iím sure doesnít help. I was wondering what the best chemical would be to treat this that wouldnít effect the grass carp and if their is anything else I can do before the pond gets out of control. Thank you and look forward to being a part of the site.

There are most likely laws about free flowing septic systems.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Clipper would work well from a cheap pump sprayer.
