Holding Tank for Black Water

[sea bird]

Hello to all liveaboards and cruisers alike out there.
We are about to finally leave our Marina Berth behind for good early Aug 2013 and head for the Med. We would like some advise about our holding tank for black water. It is stainless and would like to make sure it lasts longer than 5 years due to uric acid, does anyone know what to add or do to make the stainless last longer than the predicted life span that I have researched.


Cheers

I would expect it to last a lot longer than 5 years. But overall to me the best thing you can do for your holding tank is to give it a good flush out once in the while, maybe even put some detergent in it to help clean it out.

The best way yo make a stainless tank last longer is to replace it with plastic.
Barring that option, if fresh flush is practical for you, it will extend the life if the tank

Stainless has to breath, so do not paint coat it.and keep the water fresh. Do not let waste sit for long.
