I been using marineland GAC in a reactor for quite some time. I have a second reactor plumbed right into the one I use for GFO so it goes out one and right into the other before back to the sump. It works ok, I don't use a ton of GAC but I like to use a little as it does do great at clearing the water.
But anyway I'm looking to change what I use. I find marineland GAC to be annoying as about half of it floats rather than sinking, so I usually dump whatever floats while I'm rinsing it. I feel like its such a waste but it clogs the reactor screen if I don't dump it.
