Nope, all SPS have bleached, LPS and zoas long the bottom are closed up. No difference between the left and right of the tank.

This morning I turned off the timer for both MH's, so right now only actinics will turn on. I think i'll get a XM bulb replacement for now...

Here's a pic of the MH bulb:


The inner bulb is in tact. I still couldnt see where the glass went in the tank.

I'm thinking it's not the bulb then. It looks like you have enough of the outer casing to give you some shielding. My bulb cracked the same way, but exposed the tank to the whole inner bulb. It cooked only the corals under that halide.
