The skimmer isnt recirculating. My return pump is a Mag18, so I know I will have enough flow. It will be split for each 20L, the SPS one will get lots of flow, the anemone/clown one will get less. Controlled by gate valves, so if I see one tank isn't getting enough, just open the valve a bit more.
What should I do with the sump? If the anthelia/xenia farm won't produce, then I just won't have a fuge. Ideas? 150g is pretty big.
