I have a 55 gallon tank with a refugium/sump that is between 10-15 gallons. Basically, the water drops from the tank into the refugium part of the sump (it does go over some chemi-pure first so water isn't gushing directly into refugium), then water goes into second chamber through some drilled holes. That second chamber has an Urchin skimmer. Then the water is taken back up to the tank through an Iwaki WMD-20RLT external pump. The tubing between Iwaki pump & tank does T off so that water enters main tank in two places.
I want to start looking around for a replacement pump so that when the Iwaki dies on me, I'll have an immediate replacement. We've had the Iwaki for about 7 years now. I'd rather start looking around for a deal now and take my time than have to go pay inflated prices at a store because I need it immediately.
I do have a Tunze 7310/2 in the main tank to help with flow. I realize I could get a more powerful return pump than what I have now, but I do want to be careful not to put too much flow through the sump since the water flows directly through the refugium.
What suggestions do you great folks have for me? Since having my son 3 yrs ago and my daughter 1.5yrs ago, I have NOT had time to keep up with the latest info in the saltwater world like I used to do.
Oh, I have soft corals and a couple LPS...no SPS, and fish. So, I don't need flow for SPS.
