Eco Strong Marine Holding Tank Treatment 33 oz — Bio-Enzymatic Liquid for RVs & Boats, Odor Control & Sensor-Safe Formula

Eco Strong Marine Holding Tank Treatment is a 33 oz bio-enzymatic liquid that digests black-water solids, neutralizes odors, and keeps tanks and sensors clear.

Designed for RVs, boats, and marine sanitation systems, this professional-strength formula combines live biology and concentrated enzymes with a lavender deodorizer to rapidly liquify waste and prevent clogs. Unlike powder or packet treatments that can cake, cake on sensors, and leave residue, Eco Strong disperses instantly as a free-flowing liquid to help pump-outs finish cleaner and faster.

How quickly will this treatment reduce odors in my holding tank?

Odor reduction begins as enzymes and microbes start breaking down organic material on contact. Most users notice a significant drop in smell within hours; tougher tanks may need repeated dosing over a couple of cycles.

• Immediate enzyme action on fresh waste
• Biological organisms continue digesting solids over days
• Lavender deodorizer provides a pleasant scent while biology works

Will Eco Strong clear clogs and protect sensors better than powder treatments?

Yes — liquid treatments disperse evenly and don’t form clumps that collect on sensors or the tank bottom. Because Eco Strong is super-concentrated and free-flowing, it reduces the chance of blockages and sensor fouling compared with powdered alternatives.

• Liquid formula prevents powder clumping and buildup
• Enzymes break down toilet paper, hair, and organic solids
• Helps ensure more complete pump-outs and fewer maintenance calls

How do I use this product safely and effectively in my RV or boat?

Pour a measured dose into the holding tank after each use or as directed by the dosing instructions for your tank size. Regular maintenance dosing keeps waste liquified and odors controlled while supporting faster, cleaner pump-outs.

• Follow tank-size dosing guidelines on the label
• Add after water or use per recommended maintenance schedule
• Safe for standard PVC and macerator systems when used as directed

What makes Eco Strong different from other enzymatic treatments?

Eco Strong blends active biological cultures with a broad-spectrum enzyme package and a lavender deodorizer for a three-in-one approach: digestion, odor control, and tank cleaning. This combined strategy accelerates waste breakdown and minimizes residue better than enzyme-only or biology-only formulas.

• Bio-enzymatic system handles solids and tough organics
• Lavender scent masks odors while biology digests them
• Super-concentrated liquid avoids residue and sensor issues

Who this is for: Eco Strong Marine Holding Tank Treatment is made for RV owners, boaters, fleet operators, and sanitation professionals seeking a reliable, easy-to-use solution that reduces odors, prevents clogs, and improves pump-out performance. It’s especially useful for users who prefer liquid treatments over powders to protect sensors and plumbing and who want a measurable improvement in tank cleanliness with every treatment cycle.
