Well Maxijet are typically recommend for their ability to be turned on and off repeatedly with little wear. I suggest two Ph so you can have current coming from different directions thus creating random waves. Typically best to have them on opposite sides of the tank, pointed toward the opposite corner and crossing.
Many suggest a 10x turnover in water flow, thus 180/hr in your tank, but I suggest more for a reef tank. I would say mayber two maxijet 600s.
Just my opinion.
