just setup my brs dual reactor.
i did about 3/4 cup of carbon
and 1 cup of gfo
the reactor with the media in place.
the pump running the reactor. it is in the return chamber of my sump for now cause that was the easiest place to put it. when i have time i want to move it to the first chamber with the skimmer.
the reactor sitting beside my sump.
and all the craziness going on under the tank.
my only complaint with the reactor so far is that the push connect fittings are kind of finicky. you have to get them in just the right spot or they will leak..
unfortunately i don't have a phosphate test kit so i can't tell how effective the reactor actually is at removing phosphates.
