XM 20K, do these get whiter over time?

Personally I think the left looks much better than the right

I have the XM 14 or 15K's over half the tank. I find they do get less blue over time.

[mark]

thinking I'll be going back to 14K. I really liked the Hamilton 14k over the 14K Ushio (find yellow) but had a few blow after 6 months or less (the Hamilton's)

not sure what brand to try now

[Sebae again]

Try Phoenix 14000 k. They have a nice touch of blue.You have a great looking tank.
