We've combined all the features an advanced reef hobbyist is looking for into a compact package that is easy to use and maintain. No more messing with finicky settings or inconsistent results, the RX-1 is a solid performer that will give you years of trouble-free service.

The Eheim 1250 pump included with the RX-1 sets the standard for flow and efficiency. No other reactor in this class offers such a powerful and reliable pump. The Eheim carries a 2-year warranty.


By utilizing a box design, we're able to make the best use of space under an aquarium. The RX-1 is large enough to hold an entire container of Carib Sea ARM media (8 lbs.)!


Unlike competing products, you won't need a separate feed pump with the RX-1. The Eheim 1250 is powerful enough to serve double duty.
