Holding tank Boat and caravan

Maintenance dirty water tank. Try these products!

A waste water tank can cause odour and nuisance on board, in the caravan or in your motor home. Often this tank is treated with chemicals to counteract the smell of the rotting processes. This works, but has nothing to do with an ecological approach. In addition, the tank will eventually have to be emptied. A marina, campsite or camper van often discharges into a small-scale purification system that works with bacteria. The chemicals have a bad influence on this as they kill bacteria.

Roebic products against stench holding tank

Prevent dirty water tank problems. Do not use chlorine!

Chlorine (eg toilet duck), kills bacteria. When working with our bacteria products it is important not to use chlorine. It is best to use cleaning products that are suitable for septic tanks. We sell these at our webshopbut they are also available in the supermarket.
