Grim,
I am replacing my lights over a 75 gallon tank (6x54 with SLS reflectors not overdriven with Triads) and after reading this post and talking to Greg at Reefgeek, I was thinking about replacing my current bulbs with the following:
UVL Super Act
ATI Blue +
GE 3000K
ATI Blue +
UVL Aquasum
ATI Blue +
I have replaced 3 of the 6 bulbs and am waiting on the ATI Blue + bulbs, so I currently have my old Geisman Actinic + bulbs in place of the Blue + above.
The corals and clams seem to be very happy with the bulb changes so far. I see greens, pinks, burgandy and yellow colors more vibrantly than I saw before, and the clams are flourescing more that before.
Is there a reason that you now seem to recommend GE 6500 over GE 3000K bulb in your recent posts? I know you don't recommend the GE 3000K for a 4 bulb configuration, but have recommended the GE 3000K bulb for 6 bulb configuration earlier in the post.
Should I expect to see any difference in the look of the tank once I get the 3 ATI Blue + bulbs installed in place of the Geissman Actinic + bulbs? Will the ATI bulbs enhance the blues and flouresce the tank even more?
Would you recommend an ATI Aquablue in place of one of the ATI Blue + bulbs. If so, what is your reasoning? Is your reasoning based more on how the tank looks , or greater coral growth rates, or both?
Thanks for all of your help. Your advice before is why we ended up with the SLS T5 HO lighting system when we first got into this hobby.
