Does anyone know the effect on the biological filter medium (good bacteria) inside a canister filter when pressurized co2 is injected into the input line? Will the co2 in any way destroy or weaken the bacteria inside the filter? It seems like a good idea if co2 were injected into the intake of a ehiem canister because the medium inside, as well as the impeller would certainly brake up and dissolve the co2 and shoot it straight into the tank. Would the gasous bubbles of the co2 cause the impeller to make noise like when air is trapped inside the canister?
