    • Let your creativity bubble away with these
Pattern Name: 4 Inch
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

    • Exactly What I Expected at a Fair Price
Pattern Name: 4 Inch
These air stones do exactly what they are supposed to do. They produce a steady stream of fine bubbles, have given me no problems, and have performed reliably since I installed them. The price is reasonable, especially considering that the package includes four air stones, and I have no complaints about their overall performance or quality. They are simply solid, dependable aquarium accessories that work as advertised. The reason I gave them four stars instead of five is that, while they perform their intended function well, there is nothing particularly exceptional or innovative about them. They don't exceed my expectations—they simply meet them, which is exactly what I wanted. If you're looking for reasonably priced, dependable air stones that do their job without any fuss, I think you'll be satisfied with these. ... show more

It does not release bubbles all the way down. I soaked it first but that did not help.

Pattern Name: 8 Inch
Review Image by Jessi (Novel Heartbeat)
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

    • Terrible material also came damaged

This product looked like a good deal, 4 12” air stones for $9? Who’s going to beat that? Well the answer is themselves. They were able to beat the product up so good that 2 of the air stones weren’t even usable. The stones came in a single package for 4 stones.. these stones rubbing on each other is already going to cause them issues then you have the horrible material they used, which 2 of my air stones came pre-damaged and weren’t even usable. You can tell how flimsy these are compared to the regular legit ones. If you weren’t thinking of getting these I highly suggest you don’t due to the quality. ... show more
