DD Auto top up H2 compact

D-D H2Ocean Compact Auto Top-Up – Automatic Aquarium Water Refill System

The D-D H2Ocean Compact Auto Top-Up (ATO) is a compact and reliable automatic water top-up system designed to maintain a consistent water level in your aquarium or sump.

As aquarium water naturally evaporates, the H2Ocean Compact ATO automatically detects the falling water level and activates the supplied DC pump to replace the evaporated water.

Its dual optical sensor system, built-in fail-safe protection and visual alarm provide additional security while keeping the system simple and easy to install.
