Make sure that brain is out of the direct path of light... they DO NOT like high light. The 250 watter will kill them in no time.
Make sure there is no direct current on the bubble coral... their tissue can be damaged rather easily.
With the leathers, its a good idea to run carbon from what I have read... helps with the noxious chemicals that they release.
With the current corals that you have, I WOULD NOT suggest any SPS whatsoever.
Do you have a FTS?
