Pond Boss Forums AERATION Should I aerate? New lake, aeration, Tannins, ice etc.

Rod, in those ponds where the tannin appeared suddenly and the fish died, the tannin could have disrupted the amount of sunlight getting to the plants in the pond. Enough could have died to create a low DO event and that's why the fish died. Up in the Northern part of the US there are heavily tannin stained waters and the fish do fine. Those lakes don't have high fertility, and don't have a high fish population either........
