Bill, here is the answer to your questions. This is new, maybe because I'm using water from the tank vs. using water from the dock. I use an RV filter for the water from the dock as well as filtering the water that goes into the tank. This is the second season for the boat and the water source is the same except we just cruised Lake Michigan from Winthrop Harbor, IL to the South, to Little Travis Bay in the North and back (640 miles). The tank is a plastic material not metal (2004 Carver 360 Mariner). I want to also thank everyone for the good ideas on how to keep the water fresh. Our plans is to start the loop from Winthrop Harbor (North Point marina) in Spetember 2006.

Perhaps you can find the solution in the procedures specified by RV manufacturers for the winterization and dewinterization of fresh water tanks. The Spring commissioning (if I remember correctly) involves draining the tank(s) of anti-freeze, then re-filling with fresh water and draining by pumping out with the water pump. You also need to add chlorine based bleach for sanitizing the tank and lines. This may be need to be repeated several times to fully clear all the "pink stuff" antifreeze. I would also suggest making up a gallon or so of a water and baking soda solution to add to the tank for the final tank fill. This should be left in the tank for several days as a "sweetener." Your tank and lines SHOULD now be clean and fresh. It should be easy to keep things shipshape from that point on.
