Review on AQQA Submersible Ultra Silence Accessories Salt Water Fish & Aquatic Pets by Laura Walters

I've had this installed in my 10 gallon aquarium for almost 3 weeks now and the water is very clear. It also works as soon as I connect the pump. My only complaint is that the bubbles it produces are quite loud so I have to turn it off at night or it won't let me sleep. However, this may be because it's just below the water level, so the deeper it's submerged, the quieter it can be. Surprising for the price; highly recommended. Also note that this requires air hoses and a pump, which are not included.
