A minimum of 12 changes per hour is the recommended turnover rate for a reef aquarium. That's 190 Gal. X 12 = 2280 GPH throughput on your return. Be wary that the flow rates you see on the aquarium pumps are usually at 0 feet of head (height to which return water will be lifted). Measure the height from surface of sump to surface of aquarium, and make sure you find out the actual flow rate for a given pump at that many feet of head.

Best Regards,
Wade
