Hey guys, I have a custom loop, d5 pump, a cool 240 rads, primochill tubing, acool dual bay res, ek cpu block, 2 ek 7970 blocks, and i did the water cooling around july of this year and the coolant was red, like a sissy clear red, so a a month ago or so, i added some black dyes to make it look a little more blood red and i noticed today, all the dyes had floated to the bottom of the res and my res looks clear, almost like dirty water. should i drain my loop and change the coolant?
