Sandstone Airstone - 12 in. x 3/4 in. x 3/4 in.

I use these for my turtle tank. They are decent, but the connections to the air tubes is very hard to get on. It might be easier to use the soft airtubes if you buy these.. Maybe one of those extension things might help as well.

PURCHASED 11/25/2011 .DOESNT WORK. I HAVE HAD SEVERAL OF THESE WORKED FINE. I TRIED 2 DIFFERENT AIR PUMPS, DIFFERENT HOSE. LEVELED IT, BLEW THRU IT..ONLY ABOUT 4 " OF IT WORKS. BOUGHT IT ON AMAZON. WASTED MY MONEY.HI AS OF JANUARY 2012 IT IS WORKING BETTER ABOUT HALF OF WHAT IT IS SUPPOSED TO. I THINK THE PRODUCT SHIPPED TO ME FROM OZBO ON AMAZON MAY HAVE BEEN VERY OLD OR DEFECTIVE. I HAVE HAD MANY OF THESE ITEMS BEFORE AND NEVER HAD THIS PROBLEM.
