"But it has a definite "funk" smell"
Nah, I would've done this different from the beginning.
Nowadays, I always use a solution of silver ion fluid in our
tanks. That stuff works!
It has happpend that I forgot to use the
tanks alternatively only to find out that the STB tank in the aft had been filled 8 months earlier. NO smell at all!
Pure, drinkable
water. Bleech kills only 80 different bakteria types, silver ion over 300.
Before I started to use the silver ion solution we would always carry
drinking water in jerry cans. No longer, now we can use the tank
water for everything comprising
cooking.
Don't get me wrong, I still have a manual desalinator on board but it's now very unlikely that we'll need it.
A simple solution for potential trouble and no more need for a charcoal filter on board to boot.
OH, yeah, one good and
cheap trick to reduce water
consumption on board is a small needle valve installed in line with the
electric water pump. Tighten it your likings to greatly reduce the water flow @ the faucet. Done.
Just don't tell the crew where that valve is...
