That's cool that you asked first I'm not an expert on these corals and I'm not up to date on Sponges.
I believe that particular sponge is Silicate based and will need Diatoms and other phytoplankton. If you get a light dusting of diatoms on your glass every day then you probably have enough food in the water for it.
The softies will need a good current. Not blowing them over but not mild either. Avoid having any Stonies downcurrent from the Colt or they may not be happy.
You have a lot of additives, what are your ALK, Ca and PH levels?
