From 01.12.2018, grotamar® 82 will only be handed over to dealers and service partners and used by them. That's why the grotamar® shop is no longer online. Ask your boat service or contact our service partner.

Before buying grotamar® 82

Please pay attention

Plugged filter and visible bio sludge in the tank are often the first signs of a microbial contamination, but these can also be caused by other contamination without the influence of microbes.

If a thick layer of bio sludge is visible in the fuel tank or bio films are sticking to the wall, then it is usually too late to sanitize the tank with a shock treatment. The tank cleaning must be cleaned thoroughly! The persistent bio film need to be removed mechanically to prevent a recontamination. After an in-depth tank and pipeline cleaning the contaminated diesel fuel should be treated with a shock dose of grotamar® 82.

Please bear in mind that after the addition of grotamar® 82 dead microbes can plug the filter and an additional filter change may soon be required. The dead microbes will not be dissolved by grotamar® 82 because it does not contain acid. Acid would attack the material in the tank system.

Due to a reclassification of chemicals in the European Union, Iceland, Liechtenstein, Norway, and Switzerland by The Risk Assessment Committee (RAC) of ECHA you will not be permitted to buy or apply it directly. Instead, you can request your supplier to put grotamar ®82 in your vehicle or vessel. As long as the product is applied by them and in their name, this is considered professional use, and complies with the new rules.

Use biocides safely. Always read the label and prodcut information before use. Keep out of reach of children.
