But one time when I was out cruising forign ports, I filled up with unclorinated water. After a while my tank harbored a grusom groth. Opened the inspection ports. Hand cleaned the tank. Rinsed. Refilled the tank with clorinated water. Now I always use clorinated water and have had no more problems. > Nick
