I disconnected the vent hose off one of my fresh water tanks
and looked in the hose. Even though the hose is white, the inside of the hose is black. Does anyone else have this situation? I'm wondering if it's mold
and whether I need to replace all my hoses. I'll bring some Q-tips to the boat on Sunday and see if I can learn more. She's a 2000 Beneteau
In a related quesiton, what do people use to really cleanout the inside of their tanks
? She's on the hard
with ample water
from a nearby hose, so I can easily rinse the tanks out, so putting bleach or something in is not a problem. Should I fill them up and put some On&Off in (weak concentration) and let it sit for a few days? (I know, probably not a good idea, but I thought I'd ask.) The tanks look to be fiberglass
with stainless fittings.
