My pond is in it's third year now, stocked with CNBG, HSB, and FHM. The pond is healthy, the fish eat twice a day and are growing like weeds, I aerate 12 hrs. per day from 7pm to 7am and check water chemistry and O2 levels regularly, We will harvest a couple hundred CNBG this fall. My problem lies in the fact that I have so much life in the pond that apparently the pond produces so much DOC the algae growth is excessive. I control algae in my Salt Water Aquarium with a protein skimmer, reducing the amount of DOC available for algae growth, but I do not know how to limit DOC in my 1/2 acre pond. I obviously have too much life for a small pond, but the rate at which CNBG spawn, controlling their numbers is difficult. The HSB get their share, they are growing like weeds, however adding more will only add to the bio load, not really solving the problem. I need to remove DOCS as I really have no way to reduce DOCS. Any Ideas? ............Budster
