Are you switching to T5

Also, contrary to what some people believe, is it possible to have good SPS growth and color under T5 lighting?

I have the duel 4ft. SWC units. {SaltWater Connection, Winnipeg}. Yes, I think 6 would be better and I will likely add another fixture at some point. But also may not if everything is doing well. It would just increase growth rates, I assume. It would be neat to say, "look at this sps growth & colour with my 4 bulbs." I wont do so at the cost of any of the corals though. Because of my in tank skimmer, I cant now , unless it was a 3ft. fixture.

I am impressed with the way the corals are encrusting. Seems more so that than vertical growth. Coralline also seems to love the light. Of course, more time will tell how decent they really will be, including longevity of the bulbs. I run open top and keep them fan cooled. I believe there is a pic of them in last months FOTM, where the staff tanks were featured.

As a futher note, I like them better on this size tank then when I had halides. However if I moved and had a larger tank again, I would run halides and not the multiple banks of T-5,s some use.
