Marianne;
<P>Great points, one question though, I have read a number of articles
about chlorination and possible cancer links. Wouldn't a good quality
dechlorinating silver halide, activated charcoal water filter be prudent
to catch the extra chlorine added from the tank?
<P>Certainly chlorine has saved infinitely more lives by ensuring a safer
water supply than it may have taken from inducing cancer, but reducing
risk across the board seems prudent. So would the filter work effectively?
<P>Thanks,
<P>John

<BR>The easy part is how you can tell if the water is safe. It must
have

<BR>There is a simple test, and I will try to get the name of the apparatus,
<BR>which determines in a few moments, the PPM of residual chlorine.
<BR>If you have 5 PPM of chlorine at the tap, the water is safe from all
<BR>bacteria.
<BR>To tailor this to your boat, keep adding chlorine, agitating it, (tacking?)
<BR>and then testing until you have a residual.
<BR>I'll do some research about the apparatus and get back to you.
