AC intake. What brand of stone is it?

I have an aquaclear filter in my tank and I'm successfully and consistantly
getting about 24-30ppm of C02. I have placed the tube and diffuser up the
intake of the filter...the small bubbles get sucked in and chopped up into
smaller bubbles with the impeller. I have raised the water level somewhat
higher to match the level of the outtake.
