Keep your black tank odor-free and your level sensors reading accurately. Camco TST Fresh Scent uses a calcium nitrate formula to create an oxygen-rich environment that lets good bacteria thrive, rapidly breaking down waste and tissue while eliminating the bacteria that cause foul odors -- all without formaldehyde or harsh chemical smells. Each 8-pack gives you eight individual 4 oz treatments, enough to treat a 40-gallon tank eight times over.
Most black tank odors and false sensor readings share a common cause: waste and tissue that have not fully broken down. Standard formaldehyde-based treatments simply mask odors and can harm septic systems at dump stations. TST Fresh Scent takes a different approach -- its calcium nitrate chemistry introduces oxygen into the tank, feeding aerobic bacteria that actively digest solid waste, toilet paper, and the organic residue that coats tank sensors.
The result is a tank that smells cleaner, sensors that read more accurately, and a formula that is completely safe for septic systems and dump stations. The fresh scent is mild and non-chemical, making it a practical choice for campers who are sensitive to the sharp odors of traditional treatments.
Calcium nitrate chemistry creates oxygen that feeds good bacteria and stops odor-causing bacteria -- not just a cover-up.
Rapidly digests solid waste and toilet tissue to reduce clogging and make tank dumps faster and more complete.
Lubricates and cleans holding tank sensors so your monitor panel gives accurate level readings trip after trip.
