Maintain stable water levels with confidence using the 10 Gallon Aquarium Auto Top Off Reservoir, a premium solution designed for reef and freshwater aquarium systems that demand reliability and clean integration.

Built from high-quality domestic cell cast acrylic, this reservoir features a minimalist profile that blends seamlessly into your stand or equipment area without distracting from your display. The true 10-gallon capacity provides extended top-off intervals, reducing daily maintenance while supporting consistent salinity and system stability.

Thoughtful design details like a flush, no-warp drop-in lid, large access opening, and integrated ports make installation, refilling, and cleaning simple. Colored panels on the sides, back, top, and bottom help block light intrusion, while the clear front panel with laser-etched graduation scale allows quick water level checks at a glance.

Available in black or white, the ATO 10 is engineered to look as good as it performs — a clean, functional upgrade for any modern aquarium setup.
