Tunze 6065 wavemaker has flow rate of 6,500L/hr, so you will need at least 3 for your setup if you want SPS. Also, you must understand that it is non controllable, meaning that the flow rate is constant.
A better option would be the Tunze 6105 that has controllable flow rate (using Tunze Single/Multi controller) of 3,000 to 13,000L/hr.
