So what do you think of this idea for CO2?

[ingg]

I'm going to slowly get things together for that 33g cube.

One of the things that has always bugged me about tall narrow tanks like this is it is hard to get a good water flow from just the filter - it seems to splash the front glass too soon and not penetrate. Since I'm really wanting to try out glass lily pipes on this tank, the issue is even bigger than with a spray bar, I think.

So, I was taking a break from writing some reports this morning, and found this idea - using this little in tank Hydor Air Stone thingy as a CO2 reactor -

I'm thinking if I place it in the rear center, it may help me move water as well, getting the flow improved. Maybe.

Thoughts?

The Lily pipes will be plenty of flow if you use a large enough canister filter. Use an XP3 or something similar in size.
