Solbio Marine is the heavy-duty version of Solbio Original, developed for use on board. It contains a higher concentration of plant extracts and essential oils, and works with both fresh and salt flush water. That makes it suitable for marine toilets with sea water flushing and for larger holding tanks. Scent is orange.

The fluid breaks down waste, fats and toilet paper and prevents odours and gas build-up in the tank. It also keeps the system free of scale and urine deposits, which makes emptying easier. No chemicals or synthetic substances, so it can also be used on boats where black and grey water share one tank.

Contents 1.6 litres, around 40 doses of 40 ml.

Dosage

• Holding tank: 40 ml per 0–20 litres of tank capacity, plus about 2 litres of water. Refresh every 3 to 4 days.
• Flush water tank: 40 ml per 20 litres.
• Grey water tank: 40 ml per 50 litres, poured down the sink or shower drain.
• Cleaning: diluted in water, against scale, dirt and urine scale.

Marine or Original?
Choose Marine if your toilet flushes with sea water, if your tank is larger than roughly 20 litres, or if black and grey water run into one tank. For a cassette toilet or porta potti on fresh water, Solbio Original is enough.

Note: discharging black water from pleasure craft is prohibited on Dutch inland waters. Empty the tank at a pump-out station or an approved discharge point.
