Other than for actinic supplementation, I'm pretty much a T5 newb... so I'm looking for some advice. I've got an Elos 120. Dimensions are 48" x 19" x 19". My PGE bill hit $650 last month so it's time to swap the Maristar dual 250W HQI halide + T5 fixture out for a straight T5 setup. (I really hate to do this because I love the halides. Sigh.) I am planning on keeping almost exclusively LPS and some BTAs in this tank. All the SPS will go into the 180 in wall. I've narrowed my choices down to two fixtures: Tek Elite 6 x 54w fixture ($600 with bulbs, shield and hanging kit) http://www.aquacave.com/detail.aspx?ID=2760 Icecap Reef Illuminations 4 x 54w + 4 x Actinic LED strips ($550 with bulbs, shield, hanging kit and legs) http://www.aquacave.com/detail.aspx?ID=2713 (Promo coupon brings it down to $550 with bulbs) Both fixtures are pretty new to the market. The tradeoff is 2 extra T5 bulbs and active cooling with the Tek versus 4 Actinic LED strips with the Icecap. They're both high quality fixtures and I believe they're about equally well constructed. I think the Tek looks a bit better... I do love the look of actinic LEDs and I make a lot of use of dawn-dusk-moonlight. I'd just go with the Icecap, but I am afraid that I will regret 4 T5 bulbs on my tank. I figure I could always pick up the Tek, just use 4 of the bulbs and add moonlights if I wanted to as well. Ugh, I can't decide. Any thoughts from experienced T5 users?
