Hey my wife and I purchased a Columbia 29 Mk II and there is some
green slime on the walls of the aluminum water tank under the V-Berth
I was wondering what the best way to disinfect and clean it out.

Is there some sort of cleaner or bleach water mixture that we can put
in the tank to kill what ever is growing down there?


Any chemists here?????

Do yourself a favor. Toss the aluminum tanks and replace with 316L.
ANd DONT "shock treat" your alumunium tank with clorine bleach.

Do yourself a much bigger favor. With used boats, if ever you can, by hook
or crook, muster up all your wisdom, all your courage, and don't ever turn
a tiny, inexpensive job into a giant, expensive job unless you have a very
good reason. There will be more than enough of those to go around. So
unless Bob here give us a very good reason not to use the well accepted
bleach method, ignore him.
