Marina Extendable Air Stone Extendible 10"
Amazing wall of bubbles
Ihave this Marina extendable air stone connected to my Coralife luft pump and the wall of bubbles this stone creates is amazing. The bubbles are even with no empty spots like the cheaper air stones. It looks well built and buries itself well into the gravel. Just make sure your air pump is powerful enough to
use this air stone effectively. I highly recommend.

I bought 3 for a freshwater tank. It did not take long for the stones to harden and clog. Bad air stones will ruin air pumps. Risky!

Pitiful excuse for an air stone
I've been using standard, round air stones since setting up the tank a year ago. I thought it might be nice to try an air bar instead. Purchased this one and attached it to the pump (Whisper 100). Didn't even bother to hook up the second one. The line of bubbles coming from this stone was pitiful. I had 4 times the bubbles coming from my round 1 inch stone.
