Fields of Application
Diesel fuel/ heating oil (schock dosing) 1.0 – 2.50 l for 1000 l diesel or heating oil

Underdosing must be avoided! Due to the demand for biodegradability the effectiveness of preservatives used below the required activity level are quickly lost. Should underdosing occur on a regular basis there is the possibility that some selected microorganisms may not be killed by the preservative. In those circumstances, as most other organisms have been killed, the selected microorganisms will find ideal growth conditions.

Use biocides safely. Always read the label and product information before use.
