How not to colour your custom water cooling fluid!

    

       So most people especially those who build custom water cooling loops in their PC's, tend to use custom fluids along with those loops, and usually seasoned builders tend to deter away from that and use pure distilled water. The reason they use this is because distilled water is 99.9% pure water without any contaminants or conductive ions, the problem with "water cooling newbies" is when they want to have fancy colours tend to do one thing that completely throws them under the bus, they add food dyes or other synthetic/semi-organic substances. They reason this is a terrible idea is one word, Algae. If you are curious as to what that is, ou may read this informative article on it and where it tends to present itself most often, http://allaboutalgae.com/what-are-algae/. In this case Algae is an organism that forms inside an individuals water cooling loop that causes blockage, loss of efficiency by clogging up your pipes, and overall degradation of your components, this usually happens when you use a liquid that has various contaminants from it, also it depends on the pH level on your liquid, temperature of your PC which affects the temperature of the liquid, which helps the algae form, as well as picks up metal ions from your fitting and various other components such as block which causes a precipitate, which is a substance deposited from your solution, (your liquid) in solid form, which causes it to stick to your tubing and your fittings and cause various blockage, generally reducing the efficiency of your loop. How can you avoid algae build up? Simple, use pure fluids, a great example, distilled water, well distilled water has no contaminants in it and is non-conductive, if you also add a small amount of biocide or any other anti microbial solution, it will keep any algae from forming. Another method is to used silver coated fittings, silver is an anti-microbial metal and keeps the algae precipitate from forming inside your tubing. So to sum up, if you want to reduce the need for maintenance and algae buildup, use pure liquids with antimicrobial substances, it will keep the organism from forming and keep your loops unblocked and free flowing! Do you have any ideas for a cheap and algae-free way to colour your fluids? without causing corrosion and micro bacterial growth? Let me know!
