FAQ
What is a peninsula tank? The display is open on three sides, so it can sit out from a wall as a divider or centerpiece and be viewed from the front and both ends.
Is this a complete system? Yes. It includes the display, cabinet, sump, ReefATO+, and all REEF-SPEC plumbing. You add a light, heater, protein skimmer, and return and flow pumps to finish the build.
Freshwater or saltwater? It is engineered for saltwater and reef, though the tank and sump work equally well for a large freshwater display.
