Hello. This is my first build using a pastel coolant. I was test running my loop but turned it off overnight. In the morning it was noticeably separated, similar to what I found in the bottles (the whitish part did go into solution when I shook the bottles as per instructions). There does not seem to be enough turbulence in the loop to disperse the separated out part. There is a similar thing happening in the horizontal sections of the tubing. I am using Eiswasser Pastel Green UV-Active. I guess what I'm asking is if this is the way pastel works or is there a problem with the coolant?
