I believe its 1gram per gallon, but you want to start off with less in the beginning. I'd start with half the recommended dose than gradually work your way up to full dose over a few months

Someone may shoot me but fill a 1/8 of it up and see how that does. Screw directions on GFO haha. But wait tell you get your new test kit in so you can properly test it.

i would start slow, my reactor usually is running at 25% with GFO. In the past i was in a hurry to remove phosphates and filled up 60% of the reactor and that messed up my tank pretty good.

This last time I ran GFO, I measured "a **** ton" and ran it through. And two weeks later, I think I need a **** ton more cause the algae and cyano haven't subsided.
