Dual reactor help

[RedRaiderReefer]

Ive got a BRS dual reactor that I am having problems getting right. I bought it used and after cleaning it up and getting it installed it couldn't get any water through it. I chalked it up the pump that came with it being bad, so I replaced it with a slightly bigger one. Water still just barely trickled through and I couldn't get the gfo to tumble so I got a bigger pump again. Same problem, couldn't get the gfo to tumble with the 400 gph so I bought a new 675 gph and replaced it thinking maybe the way I plumbed it in was too much of a rise or run for the pump. Now I'm still barely getting a trickle and cant get the GFO to tumble. Anyone had this problem and found a fix?

Soak the entire thing in vinegar, switch out all the lines, probably stuff build up all over that hardened.

I soaked it in vinegar for a week, and replaced all the fittings and tubing. Ill double check theres no build up inside the the head.

I agree, it sounds like it is clogged. Might have a snail shell or something along those lines stuck in the tubing.
