SaltyTank88 Posted August 26, 2013 Report Share Posted August 26, 2013 Hello, Could anyone tell me the return pump size i would need. Im not too sure how to work it out. Water drains down a weir through 2 x 32mm bulkheads, through the sump and back into tank through a 20mm bulkhead. Water would have to travel no more then 1.6 m vertical with no bends in the line.

Mackayman Posted August 26, 2013 Report Share Posted August 26, 2013 doesnt say much as theres alot of variables with heigh and width, but anyways id go with a 4-5k pump As above, for my 2 bobs worth, I think 4-5 k is a good starting point. You can get those new buet variable speed pumps now, DC ? then ya can play around a bit with room for error. Brendan Link to comment Share on other sites More sharing options...
