The Starphire 200 gallon aquarium features ultra-clear glass to maximize light transmission for high-definition color. Corner-Flo advanced water flow technology maximizes circulation and eliminates dead-zones in the aquarium. Engineered to maximize water flow to the main filter system, water is drawn from top and bottom levels of the aquarium. All components are protected and hidden by the Corner-Flo walls. The 2 back corner walls are factory-installed and siliconed into the aquarium. The 2 complete plumbing kits include bulkhead fittings, drain, return pipes and dual Loc-Line outlet nozzles.
