ProPower Marine Tank Treatment 500ml
Stop boat toilet odours at the source and keep holding tanks & pipes scale-free – naturally.
ProPower Marine is Australia’s leading 100% natural, multi-strain probiotic treatment engineered for boat holding tanks, marine toilets, and lines. It neutralises foul odours and breaks down solid waste and calcified buildup without harsh chemicals or synthetic scents.
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.
