So the big three are furan, kana, and metro. Im trying to work out when you would want to use each individually and when you would want to combine. I know metro can be fed or dosed in the tank directly as well. I also heard to avoid metro unless you really need it. Can someone walk me through the proper use case of each individually and when combining is advised? They just seem so similar.
