Rated 4 out of 5 by Daphnia Work well, good value
I have several of these bubble disks. One has been in use for a year and still works great. They are long-lasting and attractive, compared to regular airstones. They don't stay on the bottom of the tank by themselves, but they are easier to keep down than smaller bubblers are. I bought one recently that is slightly defective - big bubbles come out the bottom of the disk, in addition to the small bubbles from the correct area. All the others that I have used have worked perfectly, and I will probably buy more of them in the future.

I like the look of this bubbler. My calico goldfish love to play in it. The only thing that Is frustrating is that it is not heavy enough. It's a small bubbler, but the air pump I have is pretty powerful, so the bubbler floats unless I put the tube under gravel, AND put bigger rocks near the bubbler. I think I would give it 5 stars IF it was weighted.

Rated 4 out of 5 by BT123 Works well, must anchor
I have had this in a 5 gallon aquarium for about 2 1/2 months. It works well and produces alot of bubbles for my white clouds to enjoy. It needs to be buried below a good amount of gravel or it will float, no matter how long you try to soak it. I have had to rebury it once, but it seems weighted down enough this time. I read that someone used aquarium safe epoxy to attach a suction cup to the bottom and that also worked.
