Most marine suppliers carry opaque hose specifically for domestic
water systems. Check out your West Marine catalog.

Seems all of the tubing sold by marine outlets for freshwater lines is
transparent, but this allows algae to thrive.
Is there a source for food grade tubing that is opaque (actually I found
some Tygon, but wouldn't take the pressure)?
It would be such a waste to wack two feet off a 50 ft length of marine
water hose....
