Sapphire ATO 5 Gallon Reservoir used for about a year on spare tank. Two small scuff areas on the side where I was cleaning too hard with a magic eraser earlier.
Laser etched handle
Two 0.25″ OD hose ports
Lid to prevent evaporation
Opening for wires and hoses
Made of 1/4″ thick material to prevent bowing
Subtle laser engraving marking the water level
Rounded and polished top
