Kris, you saw my nuked tank.
installed six AI units and didn't check the PAR readings of the 400W metal halides I had over my tank.
Lost almost ALL my SPS. My spongodes barely survived and is making a slow comeback in a different tank.
Lost my tyree true undata, my idaho grape montis, my purple haze monti, my baby blue mille, my tri color valida, and much more.
Most of these were very large colonies, 12"+.
Oh well, live and learn. I'm a dumba$$
