Level Keeper, by Reef Factory

Level keeper is a device that helps you to maintain a constant level of evaporated water in your marine aquarium.

This minicomputer monitors the water level in your sump or aquarium 24/7. If the water evaporates, the system will add an appropriate amount of water back to the aquarium. The refill process has been designed to work trouble-free. If something is wrong, you will receive a notification.
