This will probably spark a huge debate. Barry
Barry,
What I've noticed around here (we have a local reef club here in Jonesboro, Arkansas) is that t-5's are really quite awesome. I could show you some of the tanks here that have T-5's only that have some of the best looking coral's you could imagine. I use MH's on my 75 along with pc's (pc's I am growing to dislike) but on my 125 that I am currently working on to put in a wall, I will use the t-5's exclusively, because of what I've seen around here.
