Another combo idea...

Hi! I had an idea for my next set up when I upgrade my 90 gal to a 6 foot 220 gal:

2x250w HQI in the 14/15k range
2x150w HQI in the 5500/6500k range
6x80w T5 consisting in 4 pure actinic and 2 actinic+

I would pair each 250w 14k with a 150w 6000k (i.e. placed as close as possible to one another for better blending of the light spectrums...). Aquascaping would be two mounds of LR. So over each mound there would be the equivalent of a 400w HQI consisting of a 150w 6000k + a bluer 250w...
The 150w 6000k would light up only for 2 or 3 hours in the middle of the day. The 250w for about 9-10 hours and the T5s for 12 hours with an independant control for each of them for a perfect dusk/dawn effect.

Should provide nice color for both blue and pink corals AND good growth and nice light variations along the day...
What do you think of this idea?
