The Natural Solution for Fresh, Odour-Free Boating

Wastewater systems are one of the biggest maintenance challenges for vessel owners. When boats sit idle between trips—especially in warm coastal weather—holding tanks and discharge hoses quickly trap unpleasant odours.
Worse still, urine and sea water react to form struvites (hard calcification crystals) that clog plumbing lines and cause tank level sensors to misread.

Traditional chemical holding tank additives only cover up smells with synthetic fragrances and kill off essential bacteria, causing sludge and struvites to build up faster.

ProPower Marine works differently. Instead of masking problem smells, it introduces over a dozen synergistic strains of naturally occurring, friendly bacteria into your wastewater system.

Why boat holding tanks smell

Marine wastewater systems are difficult environments. Tanks may sit unused for weeks or months, especially when a vessel is stored between trips. Waste, moisture and limited airflow can create strong odours, sludge build-up and crystallisation inside tanks, pipework and sensors.

How ProPower Marine works

Boat toilet smells are not something you should have to live with.

ProPower Marine contains a proprietary blend of probiotic microbes. Once added to the tank system, the microbes work together and multiply until they reach an effective population.

From there, they help consume organic waste, reduce odour-causing compounds and support the breakdown of sludge. The result is a cleaner, better-managed wastewater system without relying on harsh chemical treatments , that simply try and hide the smell.

Frequently Asked Questions

No. ProPower Marine is designed to help manage the source of odours by supporting beneficial probiotic activity inside the tank.
Yes. ProPower Marine is suitable for fresh and saltwater systems.
Use an initial dose when starting treatment, then dose again after each pump-out according to your tank size.
Shake the bottle, mix the dose with a few litres of water in a bucket, then pour it through each toilet on board so the pipework and tank are treated.
Avoid bleach and heavily caustic cleaners in the wastewater system, as they can reduce the effectiveness of the probiotic microbes.
ProPower Marine can help soften and reduce crystallisation over time. Results will depend on the condition and age of the system.
The dose depends on tank size. Add a simple dosing table on the page and link to the full dosing guide.
