Product Questions

Would I have to remove the whole unit from sump to remove fines from new gfo?
Question by: Jarrett on Jan 12, 2017 12:07:00 PM
Great question! Yes, you would have to run this outside of the sump to remove the fine particles. The best way to do this would be in a small bowl or bucket of RODI water. :- )

Does this fit nuvo abyss 20g?
Question by: THANH TRAN on Dec 29, 2016 7:01:00 PM
Great question! This will not fit in the rear chamber of the AIO tanks. It is geared towards an in-sump application for larger tanks. :-)

  • Pops open and pukes in your sump By Fourthwind on 2/20/2017

    I am very disappointed in this reactor. I have the other reactors by IM and they work well in my AIO tanks, but this one after a week or two ejects the canister and pukes the carbon all over your sump floor. Have tried new O rings sent by IM and had several different water flow levels. Nice idea IM but poor execution. Need some way to lock the reactor in place.
  • Great design, poor manufacturing By Eric on 1/26/2017

    I've got a couple of these running in my nano, one for biopellets and one for GAC/GFO. The one I was running the carbon/gfo in decided to pop open/volcano in my sump due to a loose seal on the lid. Had the top knob break off another. Love the design, but manufacturing/QC could use a little work.
