Review on 🐠 IceCap Dual Optical ATO: Advanced Auto Top Off Controller for Hassle-Free Aquarium Maintenance by Nancy Acosta

I'm very happy with the performance of this ATO. It seems overpriced, but it includes a pump that most even in the same price range don't have. The fact that it's a complete plug and play system, requiring no programming, is excellent. It sits in my aquarium under LED lighting and works perfectly. The only funny thing is that a clownfish feeding on the surface can provoke it for a few seconds. My guess is that they create enough waves to cause low side fill. Also, the blue LED on the controller module is very bright, maybe too bright for a bedroom aquarium. A piece of tape solved this problem. The included plastic tube clip doesn't fit the rim of the glass, so I bought the Ph Orp Probe Electrode Holder, an acrylic tube holder (4 probes) that has thumbscrews and holds the tube perfectly. After all, the tube is heavily twisted in the package, but if you soak it in a bath of hot water for 10 minutes, it will become so soft that you can straighten it.
