This is probably the worst stuff you can put in a holding tank. It kills all the desirable bacteria, so waste doesn't decompose. @Peggie Hall HeadMistress will take you to task for using formaldehyde.I've tried some formeldahyde stuff that was so bad it stung my eyes when I opened the bottle, Odorlos and I've been using West Marine's ExterminOdor. The latter keeps the head smell at bay all through heated winter storage

Basically correct. I'll add a little (I have designed and operated facilities that pre-treat head and portable toilet waste for discharge to the POTW).This is probably the worst stuff you can put in a holding tank.

Muriatic (hydrochloric) acid is not a tank treatment...it's commonly used to remove sea water mineral buildup in hoses and is quite safe to use when directions for handling and use are followed.By the way hydrochloric acid is also known as muriatic acid, a very common acid found in Marine environments.
Unless of course you are on the undertaker's table.Do not intentionally expose yourself to formaldehyde.!
Be thinking about new Raritan Sani-flex hoses.I just want to chime in here with a small thing to add. When discussing the "best" treatment, it is probably worthwhile to distinguish between holding tanks that hold solid waste and those with only liquid. That is, poop or no poop. Chemically, they are quite different, obviously. I can't really offer a suggestion for either, as we have never had a problem. That might change this season. We have a new boat and it came with some odor. We just cleaned the head and immediate area (not a deep clean). We'll find out in a few hours if we need to do more, when we go back out to the boat after having sat for a few weeks.
That seems counterintuitive. Urine itself is nearly sterile and, in fact discourages a lot of bacteria. Feces, on the other hand, comes with its own supply of bacteria. I have to believe that the best treatment for one is not optimal for the other.Foswick said:

Actually they aren't..solid waste is 75% water--the same water that comes out of you separately as urine and dissolves very quickly in water. So when it comes to tank treatments, it doesn't matter whether the tank only holds flush water and urine or solid waste too. Nor does it matter whether the toilet uses sea water or fresh.

True! It is also stomach acid…. But it is not safe to mix with formaldehydeMuriatic (hydrochloric) acid is not a tank treatment...it's commonly used to remove sea water mineral buildup in hoses and is quite safe to use when directions for handling and use are followed.

a. Take a cup of urine and leave it open to the air for 3-4 days. You will probably find that it stinks worse than poop. In fact, the main operating principle of dedicating/composting toilets and clumping litter is that separating poop from pee really reduces odor. But we're going down a rabbit hole.That seems counterintuitive. Urine itself is nearly sterile and, in fact discourages a lot of bacteria. Feces, on the other hand, comes with its own supply of bacteria. I have to believe that the best treatment for one is not optimal for the other....
Please explain with links. This could be interesting. I can think of a few possibilites, but I'd like to hear where you are going with this, remembering that the concentrations are relatively low.True! It is also stomach acid…. But it is not safe to mix with formaldehyde
