No aquarium task is more tedious than adding freshwater to replace the water that evaporates out of our aquariums each day. Because of this, it's no surprise that an auto top off system (ATO) is usually the first piece of automation equipment purchased by new hobbyists. Having an ATO is particularly useful when you're away on vacation and don't have someone to watch over your aquarium or simply want to go a few days without having to think about your tank.

The ATK Auto Top Off Kit from Neptune Systems is simple to install, works with or without an Apex Controller, and has multiple back-up safety measures to prevent overfilling.
