Review on Enhancing Oxygenation and Aeration: Clscea 4 Inch Air 🐠 Stone Disc Bubble Diffuser for Aquarium Fish Tank Pump Hydroponics by Keisha Dessie

This is a great ceramic bubble diffuser with a good weight that will easily sink to the bottom and stay there. It gives off a steady stream of fine bubbles to add oxygen to the tank and would be a nice addition to my small 10 gallon tank. It is recommended to leave it for 12 hours before turning it on and you don't have to worry about it floating away while you wait or even after turning on the tank pump. It's durable and, as you can see in the video, it's quiet yet efficient.
