how do i inject co2 into a 2128 eheim filter?

inject the gas directly into the inlet and allow the impeller to break up the CO2, allowing it to dissolve in the filter chamber.

That is how to do it if you are so inclined.

My fear would be air locking the filter. Replacing the motor on a 2028/2128 would be pretty pricey.

Dont forget about carbonic acid going through the impeller could cause problems, probabally not but it is possible

Many members have "reactors" on the output side. I will be building one shortly myself.

Moved to Tucson.
