wui39 Posted January 3, 2006 Share Posted January 3, 2006 General rule most ppl agree is about 4-6 times although this can vary depending on the amount of filtration media you have. At min for the system it looks like 26000Lper hour so for this it might be best to hook up a big 1 or 1.5 hp Grundfos pump. Link to comment Share on other sites More sharing options...

Ash Posted January 4, 2006 Share Posted January 4, 2006 with that amount of water flow needed it would be wise to look at the running costs of the unit as well as parts availability. Also some redundancy might be a good thing eg. two 12000lph+ pumps in parallel with one way valves on their outlet so they can share the same return piping or maybe supplementary air driven filters?
