Just bought this reactor with media and water in it. Should I clean out all media and water and start with new or could I use the media that's in it? Should I rinse it first? Just curious but ill probably start fresh. Anyway it was a good find, picked it up for 50 but it didn't have a pump or a ph probe. Bought a Eheim universal 600 new, it was like 75. Hope I love it.
