Unique Marine Digest-It Marine & RV Holding Tank Treatment — 32 oz (16 Treatments), Bio-Enzymatic Odor Control & Waste Break Down

Unique Marine Digest-It is a bio-enzymatic holding-tank treatment that liquifies waste, dissolves toilet paper, and neutralizes odors for easier pump-outs and fresher onboard air.

Designed for use in marine and RV waste systems, this concentrated liquid formula supplies billions of activated enzymes per treatment to break down solids and reduce malodors at their source. It works in both fresh and salt water systems and is compatible with all marine toilet papers and most sanitation setups. Each 32 oz. bottle provides up to 16 treatments, helping maintain clear lines, accurate sensors, and a more pleasant onboard environment.

How does Digest-It improve pump-outs and hold-tank maintenance?

Digest-It liquifies sewage and residual sludge so solids are less likely to clog lines or remain adhered to tank walls. That makes pump-outs faster and more complete, reducing the chance of leftover material that creates odor and hygienic problems.

• Enzyme-driven breakdown of solids and toilet paper for smoother pumping
• Reduces sludge accumulation on tank walls and fittings
• Helps prevent emergency clogs and costly service calls

Will this treatment eliminate toilet smells or just mask them?

Rather than covering odors with perfumed chemicals, Unique Marine Digest-It targets the biological sources that create smells. Its bio-enzymatic action digests odor-causing residues so the foul scents disappear where they form.

• Neutralizes odors chemically and biologically at their origin
• Suitable for continuous odor control between pump-outs
• Does not rely on heavy masking fragrances that wear off

Is Digest-It safe for sensors, plumbing, and both fresh and saltwater systems?

Yes. The formula is designed to dissolve paper and solids before they can cling to sensors or level gauges, helping maintain accurate readings. It is effective in fresh and saltwater systems and compatible with common marine sanitation materials when used as directed.

• Prevents sensor fouling by breaking down build-up
• Works in diverse marine system chemistries, including saltwater
• Safe for standard holding tank plumbing and most materials

How many uses are in each bottle and how is it applied?

A 32 oz. bottle contains the equivalent of roughly 16 liquid treatments when dosed per standard directions. Add the recommended dose directly into the holding tank after use or before a voyage for continuous enzymatic action during storage.

• Approximately 16 treatments per 32 oz. bottle
• Simple pour-in application directly to the holding tank
• Works between pump-outs—use regularly for best results

Who is this for: Unique Marine Digest-It is intended for boaters, liveaboards, and RV owners who want a practical, enzymatic solution to reduce toilet odors, prevent clogs, and make pump-outs more efficient. It suits anyone maintaining standard marine sanitation systems who prefers treating the biological causes of smells and solids rather than masking problems with fragrances alone. With access to Unique Cares support included, it's a good option for DIY maintenance, seasonal prep, or daily onboard sanitation routines.
