This ATO (Auto Top Off) Lid allows you to easily convert a small Marineland 2.5 gallon glass aquarium into an ATO reservoir. Specifically designed for tight spaces, the lid is made with high-quality 1/8" and 1/4" acrylic and includes a cut-out for wiring and hoses. While it is recommended to attach the lid to the tank with glue, it is not necessary for its function.
If you require a custom cut hole for any reason, please don't hesitate to contact us. Aquarium not included.
