A few things the first color shift appears after 100 hours of usage. It'll be a noticeable color shift, then the next one happens after 250 hours of usage. With each shift the bulb will burn whiter. Your eyes won't notice it so much but take some pictures at these time frame and you will see it.

Want a real knicker twister? Look at the clam from the front of the tank, then turn off the pumps so the surface of the water stops moving and look down at it from the top.
