40 Breeder - Lighting Question

Would a 6x39W T5 (Current Nova Extreme Pro) be too much light for a 40 breeder? I'm mostly interested in keeing LPS and possibly clams. Looking forward to your thoughts.
 
I'm using a Lumenarc III Stealth Mini Pendant on an ARO e-ballast with a 250w DE Phoenix bulb on my 40b. Love it.
