Using this for a new loop i'm putting together, and in the process of leak testing i have encountered an issue with clouding after a matter of hours.

Rig was left to run for 24hours to leak test and after that period the tubing was a terrible cloudy colour, so decided to test outside the loop to rule out and contaminants from the radiators etc.

Cut 3 small lengths of tubing and placed each one in ;

EK-CRYOFUEL CLEAR
MAYHEMS ULTRA PURE H2O
TAP WATER

After approx 24 hours, this is the result ;

all 3 samples had clouded.

To rule out that the exposed edges of the tubing caused it ( even though my leak test had clouded in normal useage ), i did a second test using a couple of fittings.

This is it after approx 18 hours - EK tubing with EK Cryo liquid

and here with a piece of unused EK tubing for comparison

Clearly ( pardon the pun ) an issue with the tubing in my opinion.

Anyone alse using this ?
 
Tried some Mayhems clear tubing, exactly the same result - clouding in less than 24 hours ( not in a loop, just tubing and fluid ).

Not willing to throw any more time or money at testing tubing, so gone for EK ZMT.
