Pond Boss Forums AERATION Should I aerate? what to do, what to do?

Yes, absolutely install a bottom diffuser to ensure dissolved oxygen at the bottom. Otherwise it will stratify. An aerated pond can support a larger and healthier fish population. I think 20 feet sounds like a good depth. I'm not an expert on pond construction, but I deal with water quality issues every day resulting from poorly designed ponds. Too shallow and you could have excessive weed growth problems. 3:1 slope will prevent too much growth around the edges.
