If you can't use a powerhead, you can try snaking the end of the diffuser
line into the intake tube of your canister filter, or whatever. The CO2
will be entirely resorbed into the water by the time it comes out the
outflow tube. This method will, however, make a few filters (i.e., mine)
rattle.

It sounds like an expensive version of DIY to me.
