AquaMiracle New Innovative Rubber Air Stone for Large Aquarium, 8”x1.52” Fish Tank Air Stone 1-Pack, Air Bubbler Oxygen Air Diffuser for Pond Aerator

The media could not be loaded. UPDATE July 2024! :The seller contacted me when they noticed my poor original rating because my 3/8” tubing would fall off easily to be lost at the bottom of my pond.The seller sent me with amazing speed their new end design aerators that corrects the problem of my tubing not being able to be attached securely. After soaking in pond water for a day , I put the new ones that they sent me. They looked and felt like they were going to work better. I attached pics of the new design. I turned on the 2 of 4 outlets for my 80l air pump that had the new design aerators attached . The aerators were placed at around 3 ft deep. They bubbled up well as the video shows. After 2 weeks in 100+ degree summer heat they have stayed attached on to my 3/8” weighted tubing so I call this a great improvement in quality. I would absolutely recommend the new design. I would say their proactive customer service is 5 star and I have raised my original rating to a 5 star for performance.———————————————————-Original review:I was really hoping that these would work on our 3/8” weighted tubing. But the ends are too short to even get a small clamp or zip tie to stay on. The tubing just keeps falling off.The amount of bubbles seemed good at less than 2’ depth using one of the 4 stems on an 80L large pond aerator pump. But at deeper depths the fine bubbles did not break the surface. I ended up putting it on a pond shelf at 2’ depth.. You must follow the directions and soak it awhile before using it or it will not bubble very well. This was true of any rubber membrane aerator piece.The huge and frustrating issue is that It would keep falling off the end of my tubing just by moving it or being bumped by anything no matter how tight I put a zip tie on. I absolutely hated trying to find it in deep water after it fell off. I always knew it had come off because of the huge boiling water bubbles coming off the hose end.If they would make the 3/8” end portion longer this might solve the performance problem.I am now looking for something else because I give up on trying to get this to stay in. Sadly I bought 2 of them because the price point seemed good. So I am out the money.I would not recommend this for 3/8” weighted pond tubing .

+ High Volume of Diffused Oxygen (with the use of a quality air pump).+ Solid construction.+ Large size, perfect for larger tanks.I don't foresee having any issues with this diffuser.

My toddler likes to take bubble baths but gets unhappy when the bubbles all go away and asks if I can agitate the water to make them come back. After a minute of vigorous agitation, I decide this is insane and looked for a better solution. I hooked an air pump up to these to see if these could make enough bubbles so I didn't have to sit there and make them. They work good enough. The bubble solution we use isn't the greatest which is probably the bigger problem. These put out a good amount of what I would call medium-large sized bubbles. Definitely meant for large tanks. Both of these in a bathtub seem to be a good size. When we are done with the bath, I take them out and rinse them off and let them dry out before the next bath. We usually do 2-5 baths a week depending on the level of grime of the toddler.We have only been using them for a couple weeks. Will update if I notice any degradation or damage, but so far they have worked great. I like that I don't need to suction cup them to the tub. They naturally sink even when filled with air.

Love this. Makes fine bubbles. The connection to tubing is metal, instead of the plastic that is always breaking. Make sure you order the correct tubing . Mine tubing was a little large but my husband made it work. I plan to order another one.

Used it for my pond works amazingly well

I have super high calcium/limestone water in my tank these rubber stones are easy to clean every week by twisting and scraping lightly the deposits just fall off then I soak them in lime away for an hour or so, weekly maintenance done!

The media could not be loaded. Lots of aeration and easy to clean. Better then any others i have used

Perfect for my small pond. Fish love it.
