When it is time to change my GFO it is a PITA. Will it hurt to put it in the reactor and just run tap or RO/DI water through it for a while to rinse it off and get the dust cloud out?
I usually run a couple gallons of tank water through the reactor and new media and into a bucket. The just discard the bucket water. It saves a step, doesn't introduce any tap water, and it's a [very] small water change.
