It is a panel on rails inside the cabinet that pulls fully out so you can mount, wire and service controllers, power bars and ReefBeat modules — then slides back out of sight.

That is what makes the tank ReefMat-ready: the sock tray and divider wall come out to receive a roller filter, no modifications needed. Red Sea recommends keeping at least three sets of socks in rotation. An optional refugium wall can split the chamber into two sections, and a bubble-trap labyrinth guards the pump compartment inlet.\u003c\/p\u003e\n\u003cp\u003eOn the drain, every G3 gets the \u003cstrong\u003eReefGate\u003c\/strong\u003e, Red Sea's high-precision gate valve for fine flow tuning: the manufacturer describes a down-flow system whose water noise disappears once the valve is properly set, pairing a regulated main downpipe with an emergency bypass.\u003c\/p\u003e\n\u003cp\u003eOn the return side, the Peninsula runs piping of its own: \u003cstrong\u003etwo curved, side-mounted outlets\u003c\/strong\u003e shaped to push current all the way down the tank — a real challenge across 151 cm.
