1. Thermaltake Premium Concentrate Purple
The TT Premium Concentrate series has been specifically developed for the Thermaltake C1000 Opaque Coolant White and C1000 Pure Clear Coolant. It is a ready-to-mix corrosion protection concentrate for coloring the coolant in liquid cooling systems. The concentrate is virtually odorless and non-flammable, providing excellent protection for copper, nickel, brass, and aluminum.
2. Aqua Computer Double Protect Ultra 5l canister
DP Ultra is the result of extensive testing and contains specially coordinated active ingredients that guarantee optimal protection against corrosion and excellent cooling performance. It is produced under high-quality standards and using the highest quality, completely pure active ingredients, entirely in Germany. DP Ultra has been specifically developed for use in PC cooling systems with copper and aluminum components and is only minimally electrically conductive. The active ingredients also reduce bubble formation and optimize heat transfer at surfaces by improving the flow behavior of the coolant, leading to optimal cooling performance in your system. DP Ultra is a clear and nearly odorless solution. DP Ultra was developed directly by Aqua Computer in collaboration with Dr. Tobias Voigt. Compared to other available ready-to-use mixtures, DP Ultra achieves very good cooling performance and improves flow behavior due to its ingredients. DP Ultra is pre-measured and ready to use. We recommend an annual replacement of the coolant.

- 90% biodegradable within 10 days.
4. Aquatuning AT-Protect Crystal Blue
Ready-to-use coolant that can be added directly from the bottle into the cooling system without mixing with water. Specifically developed for closed water cooling systems, it provides effective and long-lasting corrosion protection for PC cooling systems that use different materials (e.g., copper, brass, plastics, seals). The included corrosion inhibitors work effectively and preventively, protecting the system over an extended period.
The dosing is very simple, as AT-Protect can be used undiluted to fill a water cooling system. To maintain the exact dosage, AT-Protect must not be diluted further (e.g., with water). AT-Protect is odorless, colorfast, non-flocculating, and glows in its characteristic color when exposed to UV light (LEDs, cathodes).
AT-Protect-UV-green does not contain Glysantin or glycol, and therefore does not reduce the water's heat absorption. This makes it particularly suitable for high-performance PC water cooling systems.
Warnings: Contains ethylene glycol. Keep out of reach of children, rinse immediately with water in case of contact, and seek medical attention.
Note: Since this concentrate contains dyes, it is possible that it may stain clothing or other materials upon contact. We also want to point out that dyes may fade over time, which can lead to a decrease in color intensity.

6. Alphacool Ice water
With the Alphacool Ice Water Crystal, the water cooling pioneer Alphacool fulfils the wishes of many modders and enthusiasts: crisply beautiful colours, great effects in Plexi coolers, hoses and expansion tanks as well as longevity and compatibility with the materials used. The Alphacool Ice Water Crystal series has been tested for more than 1.5 years for all possible applications in the Alphacool laboratory as well as by external testers and modders and has been found to be very good and durable. If you want to give your PC an extra portion of luminosity, you can use the Alphacool Crystal UV ice water. The UV reactivity with UV LEDs or cathodes is outstanding. With the Alphacool ice water you give your water cooling an optical highlight with best cooling performance and longevity.

10. Mayhems dyes
Mayhems Dye Concentrates have been tested under laboratory conditions for many months to provide users with the perfect product. According to Mayhems, a concentrate has been developed that is up to 50 times stronger than comparable products. High-quality, concentrated pigments ensure an enormous brilliance. To create a unique color experience, different Mayhems Dye Concentrates can be mixed together. This guarantees a custom water cooling solution.
Both the standard colors and the UV-active variants are very vibrant in their coloration. As a result, only a few drops are sufficient to give a large water loop a new coat, in this case, a beautiful blue. Multiple complete systems can be easily managed with a single bottle.
Note: It is recommended to clean your system with either distilled water or Mayhems Ultra Pure H2O before use. Since Mayhems Dye is merely a color additive for coolants and water, it lacks biocides, descalers, or pH balancers for smooth continuous operation in a production water cooling system. Therefore, it is recommended to use either Silver Kill Coil, Biocide Extreme, or comparable products from other manufacturers.
