If you stay with softies, even 250 watters will be overkill. Maybe 150s, or 175s. However, if you think that eventually you may want more light demanding corals, then go ahead and get the 250s. I would stay away from the 400s unless you plan on having a SPS tank. Very expensive to run and cool.

 

could not have said it better even 400's are un necessary for sps on a 125. 3 250's would do the job well for an sps tank.

 

What you have is good enough for the things you mentioned.
