FAQ: Can I use Seachem Purigen® in a media reactor?

This is possible, but may take some careful adjustments of the flow rate to find the right amount of tumble. Purigen® is a very light and small media, so it is very easy to eject it from a media reactor if the flow rate is too high. We recommend slowing the flow rate in the reactor to the point that only the top layer of Purigen® is moving.
