🐠 Pawfly Small Air Stone Diffuser for Aquarium Fish Tank with Pump - Bubbler Airstone Review

Bought these diffusers from Revain along with another brand to test side by side. Not only did this brand not bubble, it killed some of my plants by significantly raising the pH.

I have a Red Ear Slider tank (made from a standard 150 gallon tank) and it bubbles in the tank as expected. Not sure if the turtles like it but the water isn't worth it all the way. I would recommend.

They may not be the best on the market, but they are the most expensive. But I really like them and they work well. It's small but I only use one in my hydroponic system and it works great. Releases many bubbles. I'll buy a few more of these as soon as I have the money.

They pump a lot more air than my previous diffusers. They are also covered with small gliders. However, my fish are adapting quickly, keeping the water moving in my small tank and keeping it sparkling clean for longer. I would buy them again even if I have to replace them more often but that might be ok.

Tried these vents, they don't work. I connected them to my air pump after putting them under water and only a small amount of bubbles came out of them. After 3 hours of operation, the bubbles completely stopped. Not to mention that my aquarium has just been cleaned with fresh water. These stones are only useful for sharpening a knife.

These stone works are perfect for my needs. I put them in my smaller sponge filters to create more bubbles and deaden the bubbling noise you get from regular sponge filters. seems to work as I get a lot of air out of these rocks. No problems, shipping was fast, no problems and great product. I will be ordering more of these over time.

I bought these to replace old stones in my freshwater aquarium. I use an air pump rated for a 100 gallon tank, even though my tank is only 30 gallons. Yours worked fine for about 2 days and then stopped releasing air. I swapped out both air stones and they didn't work at all. Unfortunately, I thought my air pump had failed. I ordered a new one and it worked great with the new bar style air stone. But these still didn't work. I ended up throwing them all away and buying slightly more expensive…

These are fairly typical little cylindrical aerators that disperse the air from your air pump into streams of tiny bubbles. I thought the price was right and the quality was absolutely perfect. The nozzles were securely fastened to the stone and the nozzle fit was the standard air hose. I placed my stones under rocks and gravel so color doesn't matter, but if you don't they will be a nice dark blue. No complaints, and with a large pack I have plenty of air stones to work with. If I ever need to
