[C320-list] Water System 1996 #361

[Karl Mielenhausen]

I always trust advice from the Head Mistress, Peggy Hall, although you may
have difficulty measuring deciliters!

The official Catalina version can be found on page 19 of this pdf...

Basically similar procedures, a weak bleach solution to allow about 70 ppm
sodium hypochlorite as a shock (Peggy's works out to 375 ppm).
Pre-dilute it any way you want as long as you wind up with around 70 ppm in
the tank (taking into account that the bleach is already usually a 5%
solution).
I'm told that cruisers like to take dry pool chlorine along for this task.

I use this procedure every spring, allowing the treated tanks to sit
overnight. I empty and refill and have found it unnecessary to flush the
tanks as any residual chlorine has been diluted 100:1 and disappears
quickly.
