Red Sea REEF-FRAME 350 Aquarium System (75 Gal)
This is a large aquarium system sold for in-store pickup only at our shop. We bring it in from Red Sea as a special order, so ask us for the current lead time when you place your order.
The Red Sea Reef-Frame 350 is a fully bare, reef-ready aquarium and cabinet for complete customization: eurobraced ultra-clear glass on a marine-spec plywood cabinet in Black, White or Oak, with a sump and ReefGate plumbing in place. Lighting, skimmer, pumps, controller and ATO are left to you. It holds 74.5 gallons in the display and 93.3 gallons in total. Want it fully equipped? See the Reef-Frame MAX 350.

- Marine-spec plywood cabinet in your choice of Black, White or Oak
- Sump, ReefMat ready, with an adjustable-height skimmer chamber and refugium-ready layout, plumbed with ReefGate piping
