What can I use to purify the water in the (obviously Aluminium!) water tanks?
I have an Ovni 385 and am trying to find out what I can use to purify the water in the (obviously Aluminium!) water tanks. Bleach cannot be used as it reacts with the metal... do you have any ideas?
The manufacturer should have neutralized the tanks when new. There is a product on the market that is used to do just that but I do not know the name. I think West Marine in the US are selling that product. What people have done is use vinegar to neutralize new tanks... it seems to work.
The bad news is that chlorine in ordinary tap water also reacts with aluminium tanks and gives off a bad smell. So what I do is I use one tank for only waterfrom the watermaker, which has no chlorine, and the other tank I fill up from marinas... and always make sure when I leave the boat for any time, that I completely empty the tanks.
