Think a Seio M820 will do just nice for your tank specification of 2'. Just bounce the current of the tank wall to create circullation to the your coral. All the three corals that you mentioned don't need direct current.

Yup! If only one circulation device,than Seio 820 will do just fine,if got another PH,the 620 should provide a gentle current. Cos those LPS no need strong current mah
