The RX-1 calcium reactor represents the pinnacle in reactor technology available today. 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 RX-1 is rated for reef tanks up to 400 gallons in size.

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

By utlizing a box design, we're able to make the most efficient use of space (which is often at a premium under an aquarium). The RX-1 is large enough to hold an entire container of Carib Sea ARM media!
