My gratitude to The Grim Reefer for his input on lighting my 96x36x26 reef tank. The colors
pop and my SPS and other coral are growing like weeds...
Here is the array of bulbs I am using:
Row # FRONT
1. ATI Blue Plus
2. UVL 75-25
3. ATI Blue Plus
4. GE 6500K
5. KZ Fiji Purple
6. ATI Blue Plus
6A. R2 Signature Series Moonlight
7. GE 6500K
8. ATI Blue Plus
9. UVL Actinic White
10. ATI Blue Plus
11. UVL 75-25
12. ATI Blue Plus
BACK
I am using 2x 48" bulbs in each row to light the 96" tank.
The tank went into service on July 3, 2009. I run the actinics in rows 1,6 and 12 - 12 hours a day. The "Midday lights" are rows 2,3,8,10 & 11 run 10 hours a day, and the "Peak lights" of rows 4,5,7 and 9 run 7.5 hours a day.
Based on expected service life of these bulbs, when should I start planning to replace them? Does Grim recommend replacing some of the selections with newer technology bulbs?
373 days x 12 hours = 4,476 hours
373 days x 10 hours = 3,730 hours
373 days x 7.5 =2,798 hours
Suggestions welcomed.
