Bermuda recommends a 700-900 gph pump, Rio 1100 is only 300 gph. So I would say no, it's inadequate.
Bermuda suggests: RIO HYPERFLOW 17HF, MAG 7, SEDRA 7000
Personally, I would go with the Mag.
BTW, the Bermuda has NEVER overflowed on me.
Of course, if you add something foamy, like MelaFix or Red Slime Remover, then you need to shut it down, as per the medications' instructions. On those occasions I cheated and put a little air valve on the venturi tube temporarily so I could dial down the mix and get the aeration benefit without removing the medication and flooding the place.
