on the brs mini i setup a t and another shutoff valve so i could clean the media in the tank with as little as mess, work as possible. the t comes out of the sump and spits out the wash water from the reactor into a separate container. that way i dont have to take the whole thing out to rinse the media. i just change the media, screw it back into the reactor and turn a couple valves and out come the dirty media water. once it comes out clean i turn a couple valves back and its back to cleaning my tank.
