I have 2 vertex reactors plumbed into my manifold running off my pump. 1 of my reactors contains carbon. My other reactor contains aqua maxx ultramaxx all in one filter media. My question is shouldnt both my carbon and aqua maxx tumble while in the reactors? And if so how do I get them to tumble? I imagine I would have to turn up the knobs on my manifold and possibly turn up the power on my pump. My pump is the reeflo gold hammerhead. Only thing connected to this pump is my 125 gallon sumo(which is not filled all the way. only 10 inches of water in sump) and my 2 reactors. thank you
