My loop keeps clogging for some reason and I don't know why. This is my first custom water cooling build and I'm using the Thermaltake kit with a few add on of ek fitting and Darkside valve. Using the red Mayhem pastel concentrated with Walmart great value distilled water. I forgot to clean my radiator when I first did the build and didn't know to clean it. I flushed the system and cleaned the parts. So this is the second time this has happen and it only last for a day or two before it clogs up like in the picture. Please tell me what I'm doing wrong.
