I'm currently using distilled water with killcoil only so i thought i have to rinse it a little to get rid of the "silver" in the system.
There should be no silver in the system, other than that little coil. Silver has a reaction to the cell wall that prevents it from absorbing oxygen, effectively suffocating microbes. As coolant flows over a kill coil any microbes present are effectively killed before they can reproduce. Removing the coil removes all silver in your loop. There is no reason the silver loop would randomly obliterate itself and turn into dust that would remain in your loop.
In extent, colored coolants doesn't gunk. Copper sulphate and glycol gunks... really badly. Many colored coolant concentrates and premixes used distilled water, mixed with a small amount of glycol as their base. People like to drop copper sulphate,that is PT Nuke, Deadwater, Mayhems Biocide Extreme, etc, in as an antimicrobial. Well, as I said, glycol and CuSO4 gunk up... really bad.
It's not the coolant itself that does it, it's the addition of copper sulphate into a glycol/DI based coolant that causes the gunk.
Make no mistake, poor quality dyes/coolants will sometimes have scaling issues, and material buildup will occur but that and gunking are two very different things. Scaling shouldn't effect performance or flowrates, gunking just messes stuff up.
UV pink, and in extent UV red, also has an issue with staining things. Most dyes will stain tubing after a WHILE, but UV pink really messes stuff up. (There is no UV red, UV red is actually a red dye and UV pink dye mixed.)
EK E-Koolant has biocides, and corrosion inhibitors so there's no need for copper sulphate biocide. If you do want a colored coolant, mayhems dyes work great, fesser dyes work great too. Avoid Primochill dyebombs. I've tried many of their products before, and they're all very poorly made.Edited by ZytheEKS - 9/24/13 at 5:45pm
