Grim, it's incredible the amount of support that you give to the community. Thank you!
I have a pre-existing system that I bought from a guy recently - a standard 180 (72" x 24" x 24") with a 7 x T5, 1 x VHO retrofit in the canopy. Staggered 60" bulbs were used as 72" was not available at the time the canopy was built.
Front to back, the configuration is as follows:
T5 Giesemann 11KK Aquablue+, positions 1, 3 & 7
T5 Giesemann Actinic+, positions 2, 4 & 8
VHO (160W) URI Super Actinic Blue, position 5
T5 GE 6500K Daylight, position 6
Turn-on (sunrise-to-daylight) sequence is [5, 8] followed by [1, 3, 4] followed by [2, 6, 7]. Turn off sequence is the reverse. The groups of three are powered with IceCap 660's; the doublet with an IceCap 430.
The lighting's a bit "daylight" looking to me though I seem to get tons of PAR and my corals are growing quickly. Personally, I like the look of the Phoenix 14000K MH I have over my frag tank.
If I were to change my bulb mix (leaving the VHO and power arranged as described above), what would you suggest to give me some "pop?"
If I were to change out my T5 bulbs to 72" (but, again leaving the same power in place), would your recommended mix change?
