I'm in the planning stages of pond approx. 150' x 80' with avg. depth of 8'. One bank is about 8' higher than water level and I plan to build a water feature (water fall) for areation. What is the formula for water turnover (GPM)I need to achieve? I'm trying to size my waterfall pump to achieve the correct flow.
thanks
also can you provide guidance of what sites I need to study to help in creating the right design the "first" time.
