Biocide, Dye & Concentrates

Biocides are used in a system to kill off any bacteria. Most pre mixed fluids have a biocide element which means you only really need a biocide if you are using Distilled Water.

Dyes are perfect for users looking to change the colour of their fluid 

Concentrates are smaller bottles of fluid which can be used with pure or distilled water to make larger batches of coolant.
