I, of course, was skeptical. I've used nothing but deodorants since I started boating in my 55 ft houseboat. I thought I'd give this stuff a try, since it seemed to make sense, what with the oxidation to nitrogen and all. In fact, and much to my pleasure, it worked as advertised. My blackwater vent is on the starboard side, and , used to be, no one wanted to sit on that side if I had not recently pumped. Now there are no comments like OK, who flushed...?" I found myself a little behind the "odor ball" when a bunch of folks showed up for a long weekend, and it was HOT. As you all probanly know, heat only makes things worse. The tank was 3/4 full, and had been collecting for 2 weeks, and the day we came in, we could all detect just a bit of stink. Next ime, when I see all those folks pulling up, I'll add another shot of Odorless..."

We have used Odorlos liquid for 20 months to treat two (2) 45-gallon blackwater holding tanks in constant use. The tanks are well ventilated. The attached toilets use fresh water to flush. In those 18 months, Odorlos has NEVER suppressed the odors, and the natural bacteria in the sewage has NOT SUCCEEDED in digesting the solids. At every bi-weekly pumpout, the treated sewage appears and smells completely untreated. We have given up on this product, and are switching to Bactain, a bioactive treatment.

        Comments about Odorlos Head Chemical:

        I mix it with fresh water, 10 gals/one gall of water. and use it every time I flush instead of using sea water. It stays in the line between the back head and holding tank. It cuts back significantly on the odors that seep through the lines that, "don't weep odors".

                        The best "head" chemical additive I have ever used in my 15 years of boating. Absolutely NO odors from your head. 4 oz. does 40 gallons.
