The Sierra brand has always been the one of choice. It's not UV, but the green color will actually keep in the coolant and not your parts. Also, the stuff will lubricate the Laing pump nicely for years of trouble free operation too. The corrosion inhibitors will prevent the nasties in the loop as well.
About 10 to 15% is all it will need.
To clean the parts that have been gunked up, distilled vinegar works great! Even mix it up to flush through the loop.
I was even thinking the stuff I use in my boiler at home. It's also Propylene, but I think also has anti-microbial additives in addition to the anti-corrosives.

Get colored tubing next time man, you don't deserve to deal with this kind of mess, no one does.
I did the Dye bomb about 4 years ago, the UV effect was pretty cool while it lasted, but could care less about coloring now. I want functionality.
