Rated 5 out of 5 by CichlidMike 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!
