[C320-list] Water Tank Gunk

[wflowe3 at aim.com]

 I winterize but don't use antifreeze in the fresh water system. I drain the tanks, by-pass the water heater (pictures on the website) and use a shop vac alternating sucking and blowing to get all water out of the lines and faucets.

Gary, we do not "winterize" so we have never used the pink stuff--we just put a 
small heater on board and make certain that the insurance is up to date.  Ken

Thanks for the suggestion.   Do you also add the Clorox with the 
antifreeze in the winter?

>>> When I flushed the RV antifreeze from my water tanks last week, it took 
several cycles of adding some water, pumping down, then strainer cleaning to 
remove black sludge from both the bow and stern tanks.  The anti freeze in the 
bilge, also looked like a science project, with small white cultures floating 
around.  Both tanks now have a pint of Clorox and full to the brim, while she 
sits in her slip for a week or so.  When we get back, I will flush and rinse to 
get the chlorine smell out.   Anyone had similar experience or different 
solutions?  Some one suggested flushing with Hydrogen Peroxide, instead of 
Clorox.   I have considered using a solution of algicide from my pool chemicals, 
but not sure if it would be safe to brush teeth with later, or hazardous to the 
marine life since it has the warning on the label. The pool calls for two 
oz:10,000 gal of water.   In the storage areas under the seats in the main 
saloon, we managed to spray

around the batteries and holding tank is another story. I feel like a pressure 
washer would be easier.   Any suggestions for closing the boat in the fall, and 
spraying the storage surfaces with something like Lysol to stop the growth all 
together??
