Just after filling:
After 24 hours:
I noticed the same, I thought it was my coldcathodes getting dim but even after changing to darksides LEDs the glow is completely gone. I had to use actual UV tubing to get the effect back.
I'm using a silver kill coil in my loop with no other additives.
2 coldcathodes, new coolant. Clear tubing.
Then after I started to notice the UV effect was fading I turned to darksides LEDs.
Here you can see that the glow is gone after about 1 month of use. Even with the darksides LEDs.
To get the same effect as I did when the coolant was new, I had to go with UV tubing. Notice how the resivior is clear containing the UV blue coolant but does not glow at all.
