Just finished my first water cooled build. Being quite new I have no idea of what has happened. In some of the tubing white spots have appeared all over the tube (see images). They are not floating around, none are in the CPU/GPU blocks or the reservoir. Strange thing is that they are only in two of the tubes. Different packages so not the same tube. Everything is from EKWB if that matters. As the title says the tubing is acrylic.
Did I not clean the tubes properly? Do I have to replace them or just disassemble and fix or just leave it?
