    The original GEO reactor is back! This is the design that started the GEO product line and is what the larger models are based on. We put this back into production to offer a high quality no frills reactor at an affordable price. The 418 is suitable for aquariums up to 125 gallons and is built to fit the needs of the average sized reef. Don't be fooled by the small size these are true performers like any of the other reactors in the GEO line up, and just like the other GEO products they are built with the end user in mind.

  • GEO 510 Calcium Reactor

    GEO 510 Calcium Reactor

    GEO 510 Calcium Reactor  

    The CR510 calcium reactor will hold roughly 5 pounds of media and is well suited for reef aquariums up to 125 gallons. The diffuser replaces the standard media plate allowing the reactor to be filled from the very bottom maximizing the amount of media the chamber can hold and the high flow circulation pump permits faster effluent rates as needed for higher demand displays.

     *These reactors are built to be used with the Aquarium Plants Carbon Doser electronic regulator and does not include a bubble counter.

     Note:

    If the Carbon Doser regulator is not going to be used I recommend using the  regulator without a built in bubble counter and add a separate bubble counter. I do not recommend using any regulator that has a built in bubble counter.
