matt_a Posted January 21, 2013 Report Share Posted January 21, 2013 I'm not sure if I would trust any of these cheap pumps to do anything near their rated literage for the wattage they claim. If you are looking for a pump that size you are obviously serious. I'd be looking into something like an Onga 415. That should give you 15,000lph (real world lph) for under $550 in electricty per quarter. Otherwise I'd probably be looking at running several "10,000lph" el cheapo options.

Guest 2 Posted January 21, 2013 Report Share Posted January 21, 2013 I use a resun sealion pump their really quite good but abit expensive mine does 18000lph and they come in a few bigger sizes Ive been using mine for nearly 2 years on my 7 foot tank it's great would recommend it anyone Link to comment Share on other sites More sharing options...
Guest 2 Posted January 21, 2013 Report Share Posted January 21, 2013 You can also run them inline or inside your sump, and only use 250watts Link to comment Share on other sites More sharing options...
Ghost Posted January 22, 2013 Report Share Posted January 22, 2013 I'd get two Grundfos pumps that will do 10,000L ea at the required head and manifold them together. Most people overestimate the flow required, if you change the volume of the tank in 45 minutes, you'll be able to carry huge stocking density. That is, I'd guess one would do it, but the redundancy is worthwhile. Don't connect them inline (series) as you'll increase pressure not flow. Remember that if you do it properly, and connect in parallel (to increase flow) that you will only have one pressure line from the manifold, but you'll have two suction lines. That means that to preserve the redundancy in case of a pump failure, you'll need a foot valve on each suction line to prevent water pumping back through the dead pump.
