    • Delicate Design By wincod75 on 12/9/2015

      1.The primary issue i've had with this reactor is clogging, which seems to be common. Performing a simple google search revealed endless threads in regards to this reactor clogging. Assuming its a flow issue, my pump is an AQ 800 and from what I can tell is not adjustable.

      2.In addition, the top guard plate is plastic with small ports for flow, this is a horrid design. Once the pellets dissolve they clog the hard rigid plastic and essentially stop the flow all together. I tried placing a round piece of window screen in front of the guard, it worked for a while and clogged again. I'm currently trying a 30ppi filter pad instead.

      If anyone else has had any trouble or recommendations please post!
    • Too much power By Shootermcgaven on 5/14/2014

      Other reactors have a problem of not enough flow. Not this one. If anything it has too much power. I dialed it down as much as I could and the pellets jam to the top. I could put less pellets in chamber but I don't think it will change much.
