The Camco TST MAX RV Toilet Treatment Drop-INs are a convenient and effective choice for controlling odors and breaking down waste in RV black water tanks. These drop-ins are designed to deodorize tanks for up to 7 days with a pleasant lavender scent, which helps keep your RV interior smelling fresh without harsh chemical smells. The formula is biodegradable and safe for septic systems, making it environmentally friendly and compatible with a variety of tank materials. It also breaks down both waste and RV toilet paper efficiently, reducing clogs and helping maintain the accuracy of tank sensors.

Each drop-in treats up to a 40-gallon tank, and a pack includes 30 drop-ins, providing long-term use especially suited for various camping styles, including occasional and full-time RV use, as well as boating. The treatment is easy to use: simply drop one in the toilet holding tank. While it controls odor effectively and aids waste digestion, some users might prefer a stronger or longer-lasting scent depending on usage intensity.

As a granule form in drop-in format, it may not be suitable for those who prefer liquid treatments or need instant action. Nevertheless, its balance of odor control, waste breakdown, ease of use, and septic safety makes it a solid pick for RV travelers looking for a reliable holding tank cleaner.

Happy Campers RV Toilet & Holding Tank Treatment is designed to keep your RV bathroom smelling fresh by quickly eliminating odors using a mineral-based formula. Unlike enzyme cleaners, it doesn’t over-liquefy waste but promotes smooth flow and helps prevent clogs and buildup, which is important for maintaining your black and gray tanks in good shape. The treatment is concentrated, with each scoop covering up to 40 gallons, offering long-lasting odor control and supporting reliable waste dumping.

It’s safe to use with all common RV and marine holding tank materials, so you won’t have to worry about damage or compatibility issues. Application is straightforward—just add the granules to your tank with water after dumping, making it easy to include in regular maintenance. On the downside, although mineral-based treatments are effective, they may not break down waste as aggressively as some enzyme formulas, which might be a consideration if you rely heavily on rapid waste breakdown. Also, the product is unscented and allergen-free, which suits many users but might be less appealing if you prefer scented treatments to mask odors.

With a strong customer rating and a good track record, Happy Campers offers a reliable and user-friendly solution for RV owners looking to control odors and maintain tank health without fuss.

The Camco TST PRO RV Toilet Treatment Drop-INs are a convenient and effective option for keeping your RV's black and grey water tanks clean and odor-free. These capsules use a bio-enzymatic formula that contains natural enzymes and bacteria to quickly break down waste, toilet paper, grease, and food debris. This helps reduce clogs and keeps the tank sensors working properly. One notable strength is the fresh pine scent that masks unpleasant odors without being overpowering. The product is septic-safe and biodegradable, making it friendly for both your RV system and the environment. It’s designed to work well even in higher temperatures, though you might need to apply it more often if it's very hot.

Since these are drop-in capsules, they are very easy to use—no messy pouring or measuring needed. Camco also ensures compatibility with common tank materials like plastic, so you can use it without worry. Some users mention needing regular applications for best results, and it’s important to store the capsules below 110°F to maintain their effectiveness. The TST PRO Drop-INs are well suited for RV owners seeking a simple, no-fuss solution to maintain both black and grey tanks with good odor control and efficient waste breakdown.
