    • Better than air stone
Pattern Name: 4 Inch
Works great and puts out air better than an air stone..needs a air pump for sure to put out the wall of bubbles you are looking for but even on small pump after a few weeks you get like a small wall

    • Great for hydroponics
Pattern Name: 4 Inch
These work great in my homemade kitchen deep water culture hydroponics system in conjunction with an air pump. It's a good idea to replace these every 1-2 grow cycles because the hydroponic nutrient solution can cause issues with the air stones. Treat them like a consumable. For the price, these are a lot easier to stock up on than going through a hydroponics or pet store. ... show more

    • 50/50 some worked, others did not.
Pattern Name: 8 Inch
Some of these airstones work well, others did not. I soaked them for a full day before using them so they were saturated. My two air pumps can handle an 18" airstone without issues so it's not my pump. Luckily I bought enough of them that the couple that didn't work well weren't a big issue but it would've been nice to have them all working properly. ... show more

    • Let your creativity bubble away with these
Pattern Name: 4 Inch
The media could not be loaded. These are so much fun. Wish I could post multiple videos. I can't capture still shots very well. So far I have 3 in use out of the 4 in the package. The 1st shown is under the bridge. It is larger than the bride so it is angled with low air pressure showing a few single bubbles it gives off in the ground in front of it and then an explosion of bubbles every few seconds from the actual bridge. The 2nd is under Poseidon. His base is wider than the wand and he sits on a rock so I angled him to get the effects I wanted. It even looks like I have more air wands running than I do. The 3rd is in my shrimp tank lol. The bubbles keep my mermaid sassy floating amist their spray singing her seiren song luring the little shrimp for her entertainment and mine. I'm very happy with them and I'm sure I'll be ordering more in the near future. I've been into aquariums for 30+ years. These seem well made and durable. I have bought more expensive junk in the past to try and do what I could easily accomplish with these. And bonus at an affordable price. You have nothing to lose and everything to gain. So as far as giftable... if your friend is into aquariums or your a secret Santa and you know their into fish... your gonna be a hero. My shrimp tank is a 10 gal and the other 2 are in a 175 gal so there really isn't a tank size limit for these. The only limit is your imagination ... show more

    • Coarse bubbles, leaks air around the edges
Pattern Name: 4 Inch
I know, they're not expensive, but I expected somewhat better quality with less coarse bubbles. But as the ones I received, anyway, do not seem to be sealed around the edges, a lot of air leaks through the sides and clumps together into larger bubbles, instead of being forced out the top. I'll superglue the others, and this one as well when I get around to it - hopefully the plastic isn't the kind melted by CA-based glues, as I'm not sure the UV epoxies I have are safe for a tank with shrimp. ... show more

    • Perfect for tall tanks

Review Image by Amazon Customer Amazon Customer
My tank is 20 gallons and tall so the average sized bubbler I had was not circulating air very well. Plus I did not want it to take up too much space as most of my fish stay towards the bottom unless it's feeding time. My only complaint was how much particles there were and some scratches on them. I made sure to wash it off before I put it in the tank and it's been agreat adition and pretty quiet. ... show more

    • No pump or hose
Pattern Name: 16 Inch
Pics show a pump and hose. Package did not include a pump or hose. I have no way to use it unless I buy both a pump and hose. Lame. They are good size and well made though.
