USe of rain bar

If your output flowrate of the canister is strong enough, you may consider
using an external reactor. In this way, you can use a rainbar which will
distribute the CO2 rich water nicely and evenly without much disturbance to
the plants and at the same time there is no more the ugly CO2 internal reactor inside the water column

For my case, I used a power head with internal reactor facing my foreground plants so cannot sway (cannot live with the ugliness so take out liao).

Actually, with an external canister, is there still a need for a reactor since the filter (to a certain extent) could act as reactor too?

Havent tried this before. Think there are some bros here who did that
If my memory serves me right, think one of them is Fantasy the moderator

About the efficiency, some bros who did that can comment?
