Straight ethylene glycol works just fine. I've seen tubes that were documented to have been filled with it more than 8 years ago and it's still crystal clear and free of any yellowing.
I've seen others that had white clouds forming in the bottom of the LC chamber within a year of being filled.
The common factor I've found so far in almost ALL cloudy/tinted Marquee tube assemblies and in NONE that lasted a long time and stayed clear was that in the ones that went cloudy they all had a contaminant on the rubber bellows that could be rubbed off with a finger, on the inside surface. So I highly recommend you clean the inside surface of the bellows very carefully, and use some glycol as lubricant while you rub your finger all over the bellows surface. When there's nothing left that you can rub off, flush the chamber out very thoroughly, dry it, and then you're ready to assemble and fill.
This should help you to get longer coolant life.
