Trouble with BRS dual reactor

[Socalx45]

So I started to run carbon and GFO using the BRS dual reactor for my 125g tank. I have watched videos on how the GFO should look once its running. I get mine to tumble just a little like how it shows then in about a week its not moving at all. Eventually I turn the flow all the way up on the ball valve and it doesn't budge the GFO. Am I doing something wrong? I am using the cobalt pump that it comes with.

There probably is crud built up in the carbon chamber slowing down the flow to the gfo chamber. How is the flow coming out?

the flow doesn't seem like it has diminished at all

Then the gfo has clumped up. Have you checked your Alk/Ca/Mg levels?

Sometimes things get stuck in the tubes. I've had to take it apart and I find things stuck in there

and now that I think about it the GFO comes before the carbon
