John, did you say in another thread that your filter is pump fed from the bd via the 4" pipe or are you gravity fed to the filter and use a pump to return?

Sorry missed this one. The flow rate through a filter ideally should be enough to give the pond at least a one hour turnover so the pump flow rate should sufficient to achieve this after friction losses and head losses are taken into account.
