The pond has about 4-5 large Koi, a few hundred/thousand gold fish, and what I believe are some black catfish...though I haven't seen any since almost a year ago. (I haven't looked TOO hard...)

I haven't picked up the grass carp yet, but was pondering asking if they had any LMB...maybe I should toss some in so they can start getting rid of the gold fish? Any clue as to how many I should get or what they should cost?

I agree with you on the chemicals. I would prefer to avoid, but wasn't sure if the 8 Grass Carp would be able to keep up or if I should start protecting against an algae bloom for next summer. I'll keep them off the list for now.

Agree that aeration seems like a smart choice at this point, but the price point is an inhibitor.

Thanks!
