Feser Base Corrosion Blocker - 50mL - (FB-0055)

Mixing copper and aluminum in a custom PC water cooling system is considered a bad idea because galvanic corrosion can occur and because most water cooling components are copper using aluminum in your loop is considered a dead-end.This bottle of anti-corrosives and biocides does a good job of preventing corrosion which for people who have a mixed-metal system or an aluminium loop they want to expand with copper a requirement of their coolant.

Best option for destilled water pc cooling systems .it is cheaper and keep your system running cool all the time. I use to spend money in water cooling liquids that didn't performed as good as destilled water and it was more expensive too. So don't let them fool you buy this and put it in your destilled water and you won't regret it

I built a custom loop Jan 2014, and used only Feser Base and PT Nuke PHN. About 4-5 months in I had to change my water out because something white and fuzzy was growing in the bubble filter that came with my reservoir and my tubes were a little cloudy - though mostly on the outside. I got new tubes, removed the stupid bubble blocker, and installed a UV LED that came with my reservoir. Distilled water with the recommended amount of Feser Base and PT Nuke and I only need to refill my system now, after moving across the country and draining to transport it. I've had no issues with my setup (copper Alphacool radiator & Nickel Koolance block) in terms of anything growing, leaks, blockage, or metal transfer. The bottle could easily work for 3-4 fills with a 60x360mm radiator & a reservoir (Swiftech Maelstrom) and 6-8 with a thinner 240mm rad. Love to see nothing but clear water going through my system!
