Well guys I just wanted to report that (from my personal experience) the only 100% safe dye that does not leave sediment or other debris in the loop is the Food Dye you can get at any grocery store. The kind in the little dropper bottles. Like any dye it fades after a few months but all you do is put in a few more drops and you are good to go. It's not UV reactive. But it does provide a deep true color to the water.
I've tried all the various PC specific dyes and they all leave some amount of crud in the loop. Most also stain the tubing. Some only last a few weeks before fading. Some will destroy acrylic tops and reservoirs.
Just thought I'd put that out there for general purposes
