Review: Nice bubble stream - At first they barely produce bubbles but after a day the air stone were saturated and produced the bubbles I needed. Used them for four days in my 190 bowfront freshwater aquarium after hurricane Beryl in Houston, TX. They worked well, saved all my fish. Excellent product!! I will always have these on had for power losses.
Review: This airstone exceeded expectations. - Honestly I was a little nervous due to some of the reviews, but this airstone is a beast. The bubbles are like a fine underwater mist. 100% would recommend. Please note that I do have a powerful air pump, because I have a 120 gallon tank. I am not sure how this would perform with a low flow pump, however with my pump, this airstone is fantastic! The water is so ultra oxygenated from the stone that bubbles form on the plants! Fishsticks gills barely move because breathing is so easy for him.

## Features

- [High Dissolved Oxygen Rate]: A 3.2-inch air stone disc features a large surface area that releases smaller, denser, and more uniform bubbles, effectively increasing oxygen levels while lowering CO2 and raising PH in your aquariums, fish tanks, and hydroponic growing systems.
- [Produces Small, Quiet Bubbles]: Bubble diffuser releases compressed air into the water as tiny bubbles. This increases the contact area and exchange rate between air and water, providing ample oxygen for your fish without creating excess noise.
- [Choose for Tank and Air pump wattage]: This air diffuser area at 3.2 inches, recommended air pump power: is 3w-5w, for 30 - 70 gallon freshwater and saltwater tanks. Notice: for deeper water levels, you may need to opt for a higher-wattage air pump to ensure optimal performance.
- [High-Temperature Sintered Nanomaterials]: Durable, Corrosion-Resistant, and Dirt-Resistant for Long-Term Use. Low Power Consumption for Energy Savings and Environmental Protection. Notice: regular cleaning is recommended to ensure optimal performance.
- [Air Pump Accessories]: Includes a 3.2-inch Nano Air Disk Stone, 1 Control Valve, 2 Suction Cups, 1 T-Shaped Connector, and a 40-inch Airline Tubing. Notice: the air pump is not included.
