Our MP40 Flow Optimizer is designed with flow being the top priority. It is not a nem guard, it is a flow enhancer.
Directs flow at a calculated 12° angle
Pushes a larger wall of water instead of a narrow jet stream
Flow pattern mimics a gyre more than a traditional powerhead
Stronger than the stock cage and easier to clean

Excellent quality, and I really like the flow it produced in my 4820 peninsula. True mixed reef.
