Return Pump size and plumbing

[vder1]

Ok I will be installing a new sump when it arrives aprox. 40 gallon sump for a 135 tank . My question is what size return pump is recomended ? GPM ? I have a Little Giant 4 MDQX in service now but thinking of replacing it to a better pump. Any suggestions ?


Also will be redoing my plumbing right now I have 1" returns going to the tank . Should I change the return size ? The return lines go back to two corners standard setup on an ocianic tank. Any improvement I shoul make ? TIA

You want something in the neighborhood of 5-15X turnover rate per hour for the tank for a reef setup. So if you pump is around 1000 gal/hour (watch out! some figure is in gal/min), then it is fine for your setup. You can compensate for a smaller pump with powerheads or closeloop if it is insufficient.

You can get a bigger plumbing, but if the bulkhead is 1", you may need to change that too... which is a bit of hassle. It all depends on your choice of your pump, and I think one inch is fine for the LG4. If you want improvement, maybe try to rework the plumbing and get rid of some of the 90 degree elbow, etc.... :?
