I took apart the tempest as I'm not working on moving my rig into a nice cozy roomy Coolermast 932 HAF. I noticed my tubing has a cloudy almost chalky residue inside the tubing. How ever, the original tubing that came with the kit (the switchtech 220 h20 kit) did not have this residue. What could this be? What is the best way to clean my system out?
