Lee's Pet Products ALE12521 6-Pack Discard a Stone Disposable Air Diffuser for Aquarium Pump, Fine

I really like these bubblers. They create a very fine stream of bubbles so they work well with my bettas. They are really hard to find in the pet stores so I just order them.

Work very well in my tank and there is a lot less noise from the bubbles. it is a very nice product.

I like the quality, well made. I like that they're slimline, not bulky and easy to hide. I like that I can discard them. I had mixed success with scrubbing those other "blue" stones and they eventually had to be tossed so I don't feel bad about tossing these. The delivery was prompt. I followed instructions for "priming" the stones and once hooked up to the airline, bubbles flowed well but... they flowed mainly from top and bottom of stone and, most importantly (and the main reason I bought these) they were advertised as making "fine" bubbles but they are far from being fine. I played with the air volume to see if that helped. Nothing changed. Still made very large bubbles regardless of the force of the air. I wanted these gentle stones for my betta tank..guess I'll have to get a nano stone if I want really fine bubbles. Will keep them as backups or give to a fellow fishkkeeper.

I just recently got back into the hobby, and remembered having great success with these in the past. They were easy to use, low profit, and created nice fine bubbles. The new ones are still easy to use, and low profile but do not produce fine bubbles. The fitting is not very tight and most of the air escapes at the very top. I super glued the one for my brine shrimp tank to no avail. Still big bubbles. I guess the pore size and material are not as consistent as the old ones. In any case, gluing them kind of defeats their purpose. Oh well. I’ll find other uses for them.

Just what I needed. Great product for a great price

I use these Air Diffusers to Infuse tiny Ozone bubbles from an Ozonator into cold tap water for 5 minutes and create Ozonated Water.To Me the Ozonated Water Tastes Like Nature Intended Water to Taste !* all natural pure water straight from a babbling brook-tip- google : Ozonated Water[Ozonate = O-Zen-Ate] Eating the Water of Life : For Your Inner-Peace, Health and Longevity !FYI : Please note the above are not fda/who scientific facts :just my very old and humble opinion - ymmv ~ RHF.

These were easy to install and love the fine air flow from them.

Perfect fit for my undergravel filter system that was a different brand. Works great for 3+ months and counting. Hard to find item.
