Anchor Bubblers 6"
I have owned several of these for a long time and they work great. I never had a problem with them and they supply more that enough air in the 30 to 50 gal tanks. I highly recommed them.

A month after you use suction cups to hold down a bubbler, they start to fail. Not with this one!! The "feet" allow you to place them under the gravel and the bubbler stays in place!! I plan to order more for other tanks.

Flows great, compact size
Got two 12" to run along the bottom of the back of my tank underneath the gravel thinking that air moving upwards would be able to oxygenate the water without causing a dead zone to form. With a regulator to evenly distribute air to both sides and primed to turn on at night when my plants are gulping down oxygen, these are working great and so far haven't interfered with my plants (not even the background ones that have roots right next to the bubble bar. The only thing I wish this had was a little bit of weight to the triangular emplacements so that it's easier to place them properly along the top of the substrate. Since they float, you have to reach in with both hands and gently shovel gravel across the bottom of the emplacements while holding the bar in place or else they'll float up. Of course this wouldn't be an issue if you set them up before putting water in the tank. Just don't dislodge them once they're in place.
All in all, an excellent buy. Bubbles floating up the backside of my tank at night with the blue lunar lights on just looks incredible. Even my girlfriend who thinks this hobby is super nerdy thinks it's an impressive sight.

You better have some heavy rock or mud to bury this thing! It floats really well. Better stay with those with suction cups!
The bubble is not even. I maxed out my Whisper Model 100 and still can't get the bubble evenly across the entire length. Not to mention nobody would actually put that much air on it. With a normal bubble rate, the bubble only comes out in the first 1-2 inch.
