You will need coolant and some Anti-Microbial solution.
For Coolant, plain distilled water is best and can be found at most supermarkets. Can also get it at FrozenCPU.http://www.frozencpu.com/products/14874/ex-liq-202/Alphacool_Ultra_Pure_Water_-_1000mL.html?tl=g30c103s753
Though I would buy it at the supermarket, will be much cheaper and I think you will need a bit more than a Litre.
Anti-Microbial solution, there are two options that most people go for.
- A Biocide, its a chemical that you add to the water that kills bacteria/algae, stopping them from growing in the loop. You actually receive some free (the Deadwater) since your buying from FrozenCPU.
- A Kill-Coil, a small strip of silver that also kills Bacteria and Algae. This is what I use since its just dropping it in the res and forgetting about it, dont have to re-apply like a Biocide.http://www.frozencpu.com/products/11441/ex-tub-705/IandH_Silver_KillCoils_-_Antimicrobial_999_Fine_Silver_Tubing_Reservoir_Strip.html?tl=g30c103s1676
