Hi Dennis - It's been quite a while since I checked out your build thread; imagine my surprise to see you'd switched out your tank in toto. I've read backwards for 25 pages or so, and I promise to keep reading, but mind if I ask you a couple of summary questions?
Why'd you change out your display tank? Seems like it's about the same size as the other one.
And, I remember when you first started the build thread, you were using Radions (Gen 2, if I recall). But I see your tank now runs MH and T5HO. What did you not like about the Radions? I ask because I was thinking of getting in the car in 15 minutes and heading down to a high-functioning LFS to buy a Radion G3 Pro and mount. It would replace 2 AI Vega Colors over my 50g cube. My reason is that I've just not had consistent growth/coral health, with many of the corals coming from MH in the LFS losing their green/red/purple pigments and "browning up". That's despite near perfect water and flow conditions. Frags of these same colonies do extremely well in my 20g nano lit by 2 65w PC fluorescents.
My take is that the Vegas lack both UV and Violet spectrums, while the G3 Radion Pros have both. I considered updating the Vegas to Hydra 52s, but after reading about the lack of deep blues and the resulting color appearance (and seeing them for myself), I'm thinking that the Radion is a better option.
Yet, your thread's giving me pause. I'd also considered going to an 8-bulb ATI 24" T5HO fixture, but I'd rejected the idea because of tank accessibility and (potentially) heat problems.
Your thoughts?
