	I'm bubbling the CO2 into the bottom of my trickle filter, where
	it gets dissolved as water drips over the bio balls.  This seems to
	work fine -- there's no problem getting high CO2 concentration --
	but I have to wonder what effect this has on the aerobic bacteria
	in the filter.  I'm testing 0 units (ppm??) NH4, NO2 and NO3 with
	my sleezy Aquarium Pharmaceuticals test kit, but I've got additional
	biological filtration from an Eheim canister, so maybe all the
	bacteria in the trickle filter died long ago and it's now just a
	glorified reactor!

	Anybody have any thoughts on this?  I'm running ~20 ppm CO2.
