    Product Questions

    Can this reactor be used external or just internal?
    Question by: Josh on Jan 21, 2014 4:29:00 PM
    Hey Josh,
    They are usually run externally but there is no reason you couldn't set it in the sump if you had the room.

    Full Details

    A calcium reactor is used to maintain a balanced amount of calcium and alkalinity in your reef tank. In order to use a calcium reactor, you will need a CO2 regulator, CO2 tank, pH probe/controller, small feed pump (flow rate should be set 1-2 liters per hour) and calcium reactor media.

    • Great Reactor By Eddie on 3/17/2017

      I've had the CR3000 running on my 240 for a couple of months now. It was easy to set up and runs flawlessly. Solid build construction and the Water Blaster pumps are proven pumps. I was considering a Geo reactor prior to purchasing this one, but I'm not a fan of the dozen or so nylon screws needed to remove the top. The twist top on this reactor is quick an easy and provides a water tight seal. I did not realize how big it is. I use a Masterflex pump to dispense the effluent and an AquariumPlants CarbonDoser for Co2, considering how low both are set, I'm barely tapping this reactor's potential. The reactor design also does a nice job recirculating unused Co2. My levels have never been more steady.
    • Awesome Quality By kyle on 10/4/2015

      This is a great product with awesome build quality! I have been using this reactor for a few years now with no issues. Also it fails to mention anywhere that you do not need to buy a feed pump because the circulation pump on the reactor will draw from the feed line and make excellent pressure. I just purchased a second one to use as a sulfur reactor!
