Aqueon Pre-Drilled Standard Aquarium - 2 Overflows - Black - 210 gal

Aqueon Pre-Drilled Aquariums are coupled with either the MegaFlow or Corner Overflow System that is engineered to allow maximum water flow to the main filter system, while greatly reducing cascading water sound. The Aqueon overflow system design draws water from the surface, mid-water, and bottom levels of your aquarium providing more effective circulation, filtration and eliminating dead water zones in your aquarium.
