| My pond will be a 9x14x5 oval with a capacity of about 4,000 gallons. Can a 3" bottom drain adequately remove the debris from the bottom of such a pond? If so, assuming 1,500gph from the BD, can enough additional circulation be obtained through a skimmer (perhaps 1,000gph or 1,500gph) to have a healthy pond? At 1,000gph through the skimmer the turnover time would be a little less than 2 hours; at 1,500gph through the skimmer the turnover time would be about 1 hour and 20 minutes. |
