Re: Clean or replace holding tank?
When you pump, have them flush the tank (fill with water and repump) until it runs clear. Most GOOD pump out people do this without asking.
There are a lot of additives that help with the smell, most by either covering or killing. You wind up with Rose smelling crap, or hospital smell.
Practical Sailor magazine is a worthy subscription, they have a couple of recent articles that discuss holding tank issues. In short - increase the vent size to at least 1 inch, and add as much ventilation as you can. And always fresh and rinse with fresh.
Lessons learned are opportunities earned.
