I would get a vortech mp40W it has magnet bracket, does not transfer heat or current into tank , adjustable flow rate between 100 gph up to 3000gph !!!. Plus you can buy a battery back up that will run for 30 hours if power fails. although they are pricey about $400 and another $150 for battery back-up . Live aquaria carry them i know for sure I think marine depot aswell.
