So I bought the BRS mini reactor with the 1.5 sicce pump. I filled it up as shown with rowaphos to use to lower my phosphates. When I turned it on it was tumbling pretty good but every day I check it, the media isn’t moving at all, but water is exiting the output tube into my sump. So it is just not tumbling. And I checked to make sure it is on full power and it is, but idk what to do. Did I put too much media in it? I don’t think the tubing is too long and the 1.5 pump is strong enough right? Any tips? Thanks!
