Simple head question

I have a portable toilet system with pump out plumbing. The boat came with some RV toilet treatment solution. It's a thick blue liquid. It stung my eyes like crazy the first time I opened it. Should this be poured in the water or holding tank?

Neither. It should be taken to a toxic waste disposal site.

Try this product from Camco (amazon link). The current thinking is to use oxygenators in holding tanks. This provides more oxygen for the aerobic bacteria. It is the anaerobic bacteria that causes the sulfur odor.

What Dave said: don't do either one with it. Most RV toilet/tank products are highly toxic chemicals that are anything BUT enviro-friendly and only add a chemical odor to the sewage odor. Most claim to be bio degradable but "biodegradable" is a meaningless feel-good term used to mislead people into confusing it with "environmentally friendly"...formaldehyde is actually biodegradable...it just takes a long time TO bio-degrade, doing harm to the surrounding environment meanwhile.

The first aid instructions on tank products provide the best clue whether to use it or not. If they say something like "harmful or fatal if swallowed, may cause blindness, call poison control immediately..." avoid it!! But if they say something like "keep away from children or pets, wash hands after contact, flush eyes with water for 15 minutes after contact, contact physician if symptoms develop..." that's a good choice.

I've always been a fan of Odolos...its active ingredient is nitrates, which promote oxygen release from organic matter and often prevents odor in systems with vents that can only allow marginal air exchange. It can be hard to find in marine retail stores or catalogs, but is a LOT cheaper in RV supply stores even if you can find it from a marine source.

Btw, Dave...you DO realize that CAMCO is made in China?

Wow we have some pretty interesting facts and insight from Dave and Peggie! I figured this stuff had a high acid content along with some other nasty chemicals. This is it:

No I didn't and if there is comparable US made product I would glaldly buy it once my current supply is gone. @thinwater has been conducting experiments with off the shelf products that contain similar chemicals as Odorlos, Zaal's, and the Camco products. Perhaps he'll weigh in with his findings.

I've had it with this awful Camco stuff! The head smells awful and I've put an order in for Odorlos. Any suggestions on how to get this smell out of the head? Perhaps pump it out while feeding a steady supply of water into the tank for a few minutes to give it a good rinse?

Toilet. It's a portable that has pump out and a vent. We dumped a ton of the Campa Chem stuff in the holding tank. It seems to have helped but not totally eliminate the odor. Odorlos should be here in a day or two. I assume I should pump out before adding it so there's no potential for a chemical reaction?

Yes...not only pump out, but thoroughly rinse out the tank too...not to prevent any chemical reaction, but because Campa Chem is another one of Thetford's highly toxic chemicals ("poison" is clearly included in the label) that kill bacteria needed to break down solids and TP, preventing Odorlos from promoting oxygen release from the tank contents. You want to use tank products that work WITH nature.
