Eco Strong Marine Holding Tank Treatment 17 oz – Bio-Enzymatic Liquid, Lavender Scented Odor Control & Waste Digestion

Eco Strong Marine Holding Tank Treatment is a 17 oz bio-enzymatic liquid that digests black water solids, neutralizes odors, and keeps marine and RV tanks flowing smoothly.

Designed for boats, RVs, and portable sanitation systems, this concentrated lavender-scented formula combines live biology with targeted enzymes to break down toilet paper, hair, and organic waste. Unlike powders that can clump or coat sensors, the liquid disperses instantly to speed pump-outs and reduce buildup. Use it routinely to maintain tank hygiene and reduce unpleasant smells during storage or long trips.

How quickly will it reduce tank odor?

Eco Strong starts working on contact: enzymes begin liquefying odor-causing solids while live cultures continue digesting material over time. You’ll notice diminished smells within hours and more complete elimination after a few treatments.

• Fast enzymatic action to liquefy solids
• Biological cultures that keep breaking down waste
• Lavender deodorizer for immediate freshness
• Works in both short trips and long-term storage

Will it prevent clogs and sensor buildup?

Because the formula is a liquid concentrate, it disperses evenly and avoids the clumping common to powders and packets. That reduces the risk of residue on sensors, blocked lines, and sediment at the tank bottom.

• Liquid form prevents powder clumping and sediment
• Breaks down toilet paper and hair to reduce blockages
• Helps keep macerators and pump lines clear
• Compatible with standard marine and RV plumbing

How do I use it for best results?

Dosage is straightforward: add the recommended amount directly to the holding tank after use or before storage. For heavy use or long stays, repeat treatments at regular intervals to maintain biological activity and odor control.

• Add directly to the tank following label directions
• Use after each major use or weekly for storage periods
• Allow time for enzymes and cultures to act before pump-out
• No pre-mixing required — liquid disperses instantly

What makes this formula different from other tank treatments?

Eco Strong pairs live biological cultures with a broad array of enzymes plus a lavender deodorizer, providing three functions at once: digestion, deodorization, and tank cleaning. The result is faster breakdown of organic matter without the residue issues of powdered alternatives.

• Bio-enzymatic digestion for solids and fibers
• Lavender scent masks odors while biology removes them
• Liquid concentrate minimizes residue and clogs
• Formulated for both marine and RV holding tanks

Who this is for: Eco Strong Marine Holding Tank Treatment is intended for boat owners, RV enthusiasts, rental fleet managers, and anyone who relies on portable sanitation systems and wants reliable odor control and maintenance. It’s especially useful if you prefer a liquid concentrate that disperses cleanly, reduces pump-out times, and avoids the sensor and line problems that powdered products can cause.
