Review on JOR Energy Saving Aerator Aquariums by Walter Harmon

I have a 5 gallon table top tank. I bought 8 air pumps looking for the quietest and this pump came in second. When it is connected to the network but not connected to the network, it shows about 35 dB and this has not changed after connecting to the network. I can hear it slightly above the sound of air bubbles hitting the water surface, but it was still one of the quietest "quietest" pumps I tested. Perfect airflow for my microbubble balloon. The suction cup was small and not strong enough to hold the pump on the glass for very long. This is a normal pump. If you're not too concerned about a quiet pump, you'll love this one.
