Only thing at the bottom of mine is the yellow sponge. I think
floridaDriftwood resells the one made by Plant Guild; I know other aquatic
stores do.

I've got the almost same exact one, from www.floridadriftwood.com but
yours
looks like it's got something different in the bottom... what is it??

Hello,

I'm running a pressurized CO2 injection system in my 30 gallon planted
tank... Currently, I'm using a membrane diffuser from M3... but I'm
concerned about it's efficiency. Anyone have any other products they
would
like to recommend??

Thanks,
Troy
