Well finished sanding/painting the stand and got it and the tank in the living room now. Now, I just got all the plumbing re-connected and glued, but the one thing I'm worried about is that inside the PVC pipes, there's some salt residue from the old system that the previous owner had for his saltwater tank. I'm going to be running a cichlid tank (African to be exact) and was wondering if there was a way to flush out all the salt? Maybe have the tank running then do a water change, then re-fill the tank and put the fish in?
