4 Inch Round Air Stone Bubble Diffuser. White Premium Grade Bubbler. 3 Suction Cups to Hold in Place. 90 Degree Metal Inlet Prevents Kinks. Perfect for Hydroponics, Aquaponics, Ponds, Aquariums, etc.

Ladies and Gentlemen this is not an air stone!!! It’s a miracle of modern technology is what it is!! Haha. Just joking. Kinda! I’m 100% serious and honest when I say that since I started using this defuser, my Tomato and Cabbage that’s in my hydro bucket has doubled in just a few days. No difference in ph, no difference in any nutrients. It’s like they were stalled and had to work hard to get the right amount of oxygen from my other setup. I had a four inch stone in and I thought it was putting a good amount of bubbles in there. Not even in the same league as this little monster. I promise you all that it’s night and day difference in amount of bubbles, but also this has very small bubbles as well and that has help these plants go crazy. If you’re like me, you’ll do the research and then research some more, but this is the one I kept coming back to! Just looking at the reviews and watching all the videos online I really hoped this would work for me like it has for the others who love it. It works soooo much better than I thought it would. I would love to have a few more of these to tell you the truth. Anyway, the price was awesome to! I guarantee you will want to start a greenhouse after a week and start a business. Haha. Also, I don’t have a fish tank at the moment but I 100% would have this in my tank if I had one.Thank you Cz Garden Supply. I really appreciate you guys getting this to me so quick and checking up to see if I was happy. That means a lot to me and it shows me you all care about the customers.

Purchase this for a hydroponic garden system. I think the plants like it. Seems to keep the algae growth down.

I bought 10 of theasean all 10 leak between the plastic and the stone. Unusable...

This puts out a LOT of fine bubbles. Granted I also have a high output air pump from Hygger that really helps. But this stone is great, it puts out so many bubbles that it looks like an upside down waterfall in the tank. The suction cups provided with it keep it exactly where you put it and it moves the surface water of my 75 gallon aquarium wonderfully.

I like these a lot but two things went wrong here and are the reason that I give only 4 stars. 1 was missing all the suction cups due to the hose connector poking through the box and making holes big enough to lose them or whatever else may have been in the box.Also, I had to glue the edge where the stone meets the black plastic. Gel crazy glue worked for me. Now it blows lots and lots more fine bubbles than it did prior to me doing so. FYI let it dry for a minimum of 24hrs or according to the directions of your glue for full curing time.

This product works well enough but the packaging was ruined and open when I received it. It was also missing a suction cup.

These air stones are the first I've purchased. I'm using them for a hydroponic set up using 5 gallon buckets. These 4 inch stones provide lots of bubble action using a 7 watt air pump split 4 ways(4 four inch stones). I am very satisfied with the decision to spend a little extra money for the premium quality.

Used for hydroponics in a 5 gallon bucket.The perfect item that I was looking for

Do you want big large bubbles if so buy this if you wnat little Champaign bottle type bubble buy pawfly (more delicate on younger plants) as well a small if you want a lot of bubbles and 4inch are no cutting it / these discs are 2 small then buy an air diffuser ! (For a fish tank) and a really strong pump 500-1500gph and watch the madness that is your new favourite way to row ! :) <3 stay blessed and may your bugs stay forever frosty ;p

Works good

Product is great seller is a thief!

Was missing the suction cups to hold it down

I use for hydroponics reservoir works well. I have used 1 for about 4 months no issues. Used a new one less then 1 week and it's not working. I bought a couple of them due to how well the first one worked so well. For the price I would say they are worth it.
