I am upgrading my whole sump area with a new sump, compact theiling rollermat, might do a uv sterilizer, and a new pump. I pretty much have everything picked out other than the pump. I do love the idea of a DC pump to where I can turn up or down the flow based on what I am seeing and they use less electric (which is always nice). I am having trouble picking out what pump i want to use either a Reef Octopus Varios-6 or the Syncra SDC 7.0 wifi pump for my tank. My tank is a 120 gal tank with duo overflows and returns, I am running an Apex classic to help monitor the tank and control most of the equipment. If you have a better choice than what I picked please feel free to share as well
