I'm sure that I'm not alone when I say those Hagen bubble ladders are big and ugly. Are there any other options that people prefer? I was thinking that running the tube through an air stone underneath a rock would work. The CO2 would collect in the pocket under the rock and slowly leak out/mix with the water. Is this a good idea, or should I work on a way to hide the bubble ladder when I get it all set up?
