A calcium nitrate holding tank formula that kills odors at the source, accelerates waste and tissue breakdown, and keeps your tank level sensors reading accurately -- without harsh chemicals, formaldehyde, or overpowering smells. One 32 oz jug treats a standard 40-gallon black tank for up to 8 weeks of weekly dosing.
TST Fresh Scent uses a calcium nitrate base to introduce oxygen into your holding tank. That oxygen environment allows aerobic (good) bacteria to thrive and out-compete the anaerobic bacteria responsible for the hydrogen sulfide odors that make RV black tanks notorious. The result is real odor elimination -- not just masking -- with a light, fresh scent rather than the overpowering perfume or chemical bite of older formaldehyde-based products.
Unlike formaldehyde treatments that kill all bacteria and rely on chemical suppression, the TST formula works with your tank's biology. It also coats sensors with a thin lubricating layer that prevents waste from sticking and causing the misreadings that plague nearly every RV owner at some point.
Rapidly digests solids and toilet tissue to prevent pyramid plugs and stubborn clogs at the tank outlet.
Lubricates and cleans probe sensors so your tank monitor gives accurate readings instead of perpetual "full" alerts.
Safe for septic systems and approved dump stations. No formaldehyde means no disposal restrictions at most campgrounds.
Works in hot summer and cool fall conditions. For temps above 85 deg F, simply increase dosage by 2-4 oz to compensate.
Correct dosing is the single biggest factor in treatment performance. Too little and odor control suffers; the formula is concentrated enough that a little goes a long way when used properly.
TST Fresh Scent is versatile enough to handle every liquid waste situation in an RV or marine setup:
