Oh, I forgot to mention, these are in my 50, a link to where stats can be found is in my sig.
Yea, I've read that about them. I thought my 2X96 coralife fixture should be enough (even though the reflectors are crappy). I actually ordered new bulbs this morning, as these could use replacing. Maybe that will help. Thanks for the input!they need really strong lights.. Mine does that too but in my low tech tank where I use sunlight, it's doing pretty good.
