Auto Top Off Systems

If there is one automated accessory we suggest, it is an Auto Top Off (ATO) System. When a Saltwater Aquarium evaporates water, the salt is left behind increasing the salinity. Maintaining a constant water level in your aquarium or sump can lead to much healthier fish, coral, and even better performance for your protein skimmers and other equipment. Auto Top Off Systems will normally include a controller that connects to one or a few sensors and then a connection for a pump to transfer the water from a reservoir to your aquarium. The sensors in your aquarium will be able to sense the water level and when it drops low enough, the pump will turn on, pumping fresh water into your aquarium until the desired water level is reached.
