Medium Bubbles: Produces abundant dense bubbles to aerate your water reservoirs. A great way to increase oxygen solubility in your aquarium and enliven the aquatic lives.
Model: ASD100; Jetting volume: 12 L/min; Recommended air pump power: > 4 W; Inner diameter of tubing: 3/16″ or 3/8″. Great for aquariums, DWC systems or ponds.
Reliable Material: Made of mineral material and sintered at a high temperature, it causes no effect to the health of your aquatics. Keep fish or roots growing healthily.
Stable in Water: Measures 4.1″ D x 0.7″ H and weighs 7 oz, which helps it sink to the bottom easily. And the 3 suction cups tightly suck the tank to make it sit stably in water.
Easy to Use: Soak the stone completely in water for 1 hour before use. Clean it regularly with a brush as it gets clogged after weeks or months of usage.
Customers say
Customers find the air pump works well, particularly for 5-gallon DWC hydroponic setups. The bubble size and air flow receive mixed feedback – while some appreciate the nice amount of bubbles and good airflow, others report bubbles only appearing on one side and air only coming out one side. The quality, value for money, and suction cup quality also get mixed reviews, with some finding it a good value while others consider it overpriced.

Work well for plant water
Good product- I recommend getting a tubing elbow for each. They do not like to sit on the bottom flat, more so the tub doesnât . A little easier to place flat on bottom of your turn pressure off. Used for aeration of plant nutrient reservoir.

Works great for aerated fish holding well
Used these in conjunction with a battery powered bubbler and an old cooler to make a aerated holding well for fishing. These disc’s put off sufficient amount of bubbles to keep the water fresh in the cooler.

Airflow.
Works a lot better than most other airstones.

Difference between pawfly and regular airstone
Hereâs a comparison of pawfly air stone vs regular air stone and how much air and the distribution looks like.Air seems to circulate more and more disbursed with the pawfly than the regular air stone which shoots straight to the top.You do need a good pump though or else your pawfly wonât work properly

BEST of the best of the best!!!
I’ve been using Pawfly nano stones exclusively for 4 years. These are my secret weapon in my garden!! I swear by these! You can put all the air in you want, but if it’s not dissolving it’s worthless.For best results, use a far bigger pump than needed and dial it way down to proper pressure. Clean the stones WEEKLY or they will clog. Don’t turn the pressure too high or the stones will be forced out from the housing.In 4 years I can honestly say I have never seen a single one of the issues anyone mentions in these reviews. NOT A SINGLE ONE!!! They are ALL user error. I wouldn’t even waste my time or money buying another brand or type of stone. PERIOD.

Stopped working.
I did not realize it was possible but these both stopped working in less than a month. I tried cleaning them and using a stronger pump but they simply wouldn’t bubble. It was a waste of money for me and I will never buy them again.
