  • Creates lots of bubbles for low cost
Pattern Name: 16 Inch
Works very well, easy to install. Two produces plenty of bubbles for my 55gal tank.

  • Looks amazing!!
Pattern Name: 8 Inch
The media could not be loaded. I saw reviews say that the bubbles don’t come out even, and they don’t, but I personally don’t think that takes away from the beauty of the bubble curtain. It looks fantastic in my tank, and I’m hoping it will be entertaining for the figure 8 puffer I plan to get when this tank cycles! I also saw that it clogs pretty easily, so I’m prepared for that. Half my tank is sand, so that may clog, but the pack of 4 was reasonably priced so I think it will still be worth it even if I have to replace it every few months. I bought the little $5 Tetra Whisper pump and it has plenty of power to create a strong bubble curtain! The only complaint I have is that it makes the top of my water very fizzy, so the underside of my canopy is constantly soaked. If I had any holes in the back of my lid over where the stone is, it might pose a problem with water splashing out of the tank. ... show more

  • Good for the money
Pattern Name: 12 Inch
I got four 12 inch bars. I only installed three. Two worked great and one only had bubbles out from the first half. But don't get me wrong, it's still great and doing good job. Four bars for about $12 is a great deal. They still performed much better than the topfin I got from petsmart for much higher price. I recommend this product for under $15. ... show more

  • Nice and heavy duty
Pattern Name: 4 Inch
these long air stones are great. They allow your air pump to put more bubbles into the water than just one little round air stone. The bottom part is weighted which helps keep the stone from floating.

  • 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

  • Works
Pattern Name: 8 Inch
I am not using the suction cups but rather have it under driftwood to hold it down onto the gravel. Nice bubbles and my fish are happy again. Fits great in a 10 gallon tank. You must soak the stone/bubbler for at least 15-30 mins in water before hooking up your air line. That is the most important tip I can give you. ... 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

  • The product
Pattern Name: 4 Inch
I won’t say it’s a bad buy because I don’t know if I’m doing something wrong but what I can say is none of the 4 air stones worked while sitting at the bottom of the tank I have a 20gal deep and 40-60 gallon air pump which I connected them to
