cobbobby the 250a is the exact same skimmer as the 250 with the 2 sicce pumps. the only difference is that the 250 has one askoll pump on one of the sicce intake ports and the other is capped off. the "mod" is where msx caps the 2 sicce intake ports and drills and taps a 1" port to attach the askoll to. this is the only way that you get the full 80+ scfm out of the skimmer.
and if i can afford to get the skimmer with the askoll upgrade then i would spend the extra 20 and get the 300A. but if i dont have the extra cash i was wondering if the 250 with sicce pumps would be enough for a 180 gallon total system sps tank?
thanks all.
