Water from your overflow splits into two paths: one feeds the protein skimmer chamber, the other feeds a dedicated refugium where macroalgae and copepods strip nitrate and phosphate, and both rejoin in the return section. Three sizes, each with drain bulkheads, flexible drain hose and a filter sock in the box.

One channel carries water through the skimmer chamber, where a protein skimmer removes organics. The other channel feeds the refugium chamber on its own path, so macroalgae get time to absorb nutrients and copepods can breed without sitting in the skimmer's blast. Both channels meet in the return chamber, where your return pump sends water back up to the display. A removable drain and return lid keeps salt spray and noise down.\u003c\/p\u003e\n\u003ch2\u003eFeatures on Every Model\u003c\/h2\u003e\n\u003cdiv class=\"aq-features\"\u003e\n\u003cdiv
