[QUOTE=g-ray;688242]To be honest chris I have never done that I moved some sps lower in my tank but never really went out of control with it. I went from pc to current 4x54 t5 and then to 6x54w tek light.[/QUOTE

I'm just worried because it's Biocube and not that deep, another question should I worry about heat issues, should I look for fans, again I was thinking of goin open but kinda worried about jumpers so I was thinkinking of goin with a top, not sure to go with glass or acrylic(warping issues?)

good to see your still around Gary
