Review on 🐠 Enhance Your Aquarium with the hygger Mini Intelligent Auto Top Off System - Magnetic Mount, Controller, and Pump - Ideal for Saltwater Reef Tanks up to 60 Gallon - Easy Water Refill! by Angela Sanford

available I have an AIO aquarium that has a black rear filter chamber. The sensor for ATO is actually a big electronics box and the sensor is the glass on the back that needs "CLEAR GLASS" to see the water level. I'm not going to mess up a $300 tank to make it work. You'd better buy another good ATO brand. In addition, the hose holder also bends the hose. Pros: Easy to install Cons: Everything else if it works. Update: The seller has updated the information.
