Replaced with new T5 lamps 2 weeks ago.
Lamps age: 2 weeks
Light fixture 9 in. from water level
The lamp combo from front to back

ATI procolor
ATI aquablue spec.

The only difference is I took out one UVL aqusun, and replaced with ATI procolor. I will run this combo for a while to see if I like it? May try other combo later.
