What's the best 'product' for adding to nb holding tanks (apart from the

I'm sick (almost literally) of the pooey pong emanating from my huge holding
tank...the previous owner was very much against 'chemicals'....I'm not so
sensitive to the environment outside my nb, but IT STINKS !

Is it Elsan Blue...green...what ?

Go for the extra concentrated version or what ?

Any advice gratefully received.



Our holding tank made no smell at all when we bought Lionheart. We used
her for 6 months doing exactly what I had been told by a toilet expert.
i.e. we put *nothing* in it other than human waste.

Then at a certain pump out they put elsan blue in without asking us.
Within 2 weeks it stank to high heaven.

Ventilation and aerobic bacteria stop it smelling. The bacteria breaks
it down to something far less repulsive.

Anaerobic bacteria makes it smell.

Eslan blue kills the aerobic bacteria therefore as soon as you put it
in, it starts to stink. You then have to put more and more in to keep
the smell at bay.

It took 5 clean outs and 6 months to get the tank back to clean, and
not smelling.

That's one of the acknowledged experts on marine toilets. Apparently.
