I am not familiar with the current Euro Reef line up but they are supposed to be pretty good, if you are seeking more performance I doubt that a 9010 or 9015 will do more, it will likely be about equal. I am not sure I recommend this unless you can be more specific about why you are unhappy with the Euro Reef. The 9010 and 9015 are really the same basic unit, the 9015 has a taller riser and bigger cup enabling you to open the air adjustment all the way and get the maximum potential. In general I prefer the 9010 which can always be upgraded, but again, I don't see it outperforming a small Euro Reef, it may be quieter and more consistent but you won't gain any performance.
