Don't know what to do, some input on lighting please.....

Holly crap I almost died when I read this and the other post. I really think people need to do some research before they start blasting off facts. Look at the par values for the T5 bubs that are out there. The highest par bulbs on the market are KZ, ATI, AQUA SCIENCE, and some UVL. There isn’t any bulbs on the market then the Kz or ati bulbs.

KZ NEW GEN 315
KZ CORAL LIGHT 340
KZ FIJI PURPLE 330
KZ SUPER BLUE 310
ATI BLUE PLUS 320
ATI AQUA BLUE 330

Also have most of you even looked at a chart showing the spectral intensity the corals photosynthesize at? Well I will have to show you then. Corals only use blue and red spectrum for photosynthesis. The problem isn't your bulbs it’s your fixture. You should have better reflectors and more bulbs across the tank. I suggest a 6 bulb or 8 bulb tek or a 6 bulb ati fixture. 4 t5’s will not truly cut it for sps and clams unless they are mid way up or higher.

Before spending money on changing the fixtures, I would suggest just trying a different bulb combo, replacing maybe one or two bulbs only for now. See how that goes.

I am a fan of the MH, but I must say many of you have gorgeous setups and happy coral with only T5HO, so getting the right config and right number of bulbs is the key here. I wouldn't just change to MH, just yet, if you don't need to.
