okay im building a pond 8X4X2ft,,,i think im going to use bulkheads for the overflow then into a sump then a external pump to the tank any suggesttions for what size pipe and what size pump
i was thinking i sump but 2 pumps for better flow....it works out to be the same......so with X2 one inch bulkheads thats 600 gph each so i need 2 600 pgh or lower pumps....
i would def. go with 1 pump split, but i would use larger bulkheads. that way if one gets clogged your ish doesnt overflow. been there had that problem. but had safeguards in place.
