Got some of this yesterday. Any recommendations on how to run it in a reactor. Was gonna use a two little fishies but this stuff goes right thru the filter pads. i just threw it in a media bag in the sump but know it would be better in a reactor. my total system volume is 250 gall. and they recommend 1.5 cups. i thought you were supposed to run water as fast as you can thru carbon without it tumbling. that would be really slow with this stuff
