2 reviews for GEO CR612 Calcium Reactor

  1. Rated 5 out of 5

    This is, by far, the most beautiful reactor I have seen or utilized in this hobby. Every detail is sleek, modern and well thought out. I have and love an older 612 model and I was not sure how I would like the new white version in person but once unpacking I instantly fell in love. The pump plate, black silicone and color coded tubing are just a few highlights that you don’t see in other reactors. The uniseal vs older threaded elbow is a plus and even the etched GEO is etched in this reactors lid stand out in a top shelf kind of way. There is only one name in the game for Calcium Reactors and thats GEO hands down. I’m as stoked to show this off as I am colonies of Acros. Now I am looking at the rest of their range to see what will be under my stand. Fantastic job GEO.

    When growing up GEO always comes to mind for Calcium Reactors.
    Last fall I was ready to migrate over to one and reached out to GEO.
    GEO took down all my specs and we went with the CR612 for the main reactor and the SMC415 for the second stage.
    Running the large Reborn media with 10% of ZEOmag in stage 1 and the small ARM media in stage 2.

    Not only is this the most beautiful setup, but my SPS are growing more too, from the constant alk.

    GEO,
    Thank you so much for taking the time and bringing the system together for a smooth transition.
