This calculator will help you to estimate the cost of operating any
given electrical pump, based on the average KWH (kilowatt hours)
used per day, and on the average cost per KWH charged by your
electric company.
Filters that have not had water circulating through them for the winter should be cleaned well before turning the pump back on this spring. Cleaning will remove toxins that can develop from waste breaking down in the filter in the absence of oxygen. Once your filter is up and running, seed it with beneficial bacteria.
