I would think your ok, just run a skimmer and keep up the water changes. Thats what I do.

Oh yea, side note: I previously said that my Moorish Idol was doing just fine with my clams...well disregard that!!! The past 2 days he has been picking at all of them!!! My Nori shipment doesn't come in until Monday, so I am grabbing an emergency pack at HEB. Hopefully, thats all it will take. I will keep you updated.
