Blue Marine “Acqua Blue” is a high-quality sanitary additive designed for use in chemical toilets and portable WC systems. This blue fluid contains special bio-active ingredients and deodorizers that work together to break down waste products and keep the holding tank clean and odor-free. Its formula is engineered to be effective without damaging the plastic parts of the toilet or the seals.
Action: After adding Acqua Blue to the lower waste tank of a portable toilet (or the holding tank on board), the solution begins to break down solid waste and toilet paper into more fluid components. This prevents the formation of solid sludge and makes subsequent emptying much easier. At the same time, the special fragrancing and antibacterial agents neutralize odors that typically build up in the closed tank. The result is a significantly more pleasant environment in the boat’s head or RV bathroom, even in warm climates.
Usage Instructions: Blue Marine Acqua Blue is highly concentrated, which means it is economical to use. The typical dose is about 50–100 ml of fluid per ~10 liters of tank capacity (or as directed on the bottle). Simply pour the recommended amount into the empty waste tank, add a bit of water (if required), and the toilet is ready for operation. With each use, the product continues to work, keeping the waste in a liquid/slurry state and preventing gas build-up that often causes bloating and the risk of splatter when emptying.
Compatibility: This fluid is compatible with all types of portable chemical toilets – for example, popular brands like Thetford, Dometic, etc. – as well as fixed marine toilets that utilize chemicals in their holding tanks. It does not contain harsh chemicals like formaldehyde that could damage seals or harm the environment. On the contrary, the formula is highly biodegradable, and after recommended use, the waste can be disposed of at designated pump-out stations without issue.
Advantages: Using Blue Marine Acqua Blue greatly improves the hygiene and convenience of using a chemical toilet on board your boat or during camping. Eliminating foul odors means that even on long trips, the interior space remains fresh. Moreover, breaking down the waste reduces the risk of clogs in the system and makes cleaning easier – when it’s time to empty, the contents are more liquid and pour out smoothly.
In summary, Blue Marine Acqua Blue is an essential supply for any chemical toilet, providing comfort for users and keeping the system in good condition. With two available sizes (2 L for occasional use or 5 L for seasonal/extended use), you can stock up according to your needs and always count on a clean, well-functioning toilet on board.
