Now I know why your so chipper, and where all the algae in my tank came from I am running 1/2 cup GFO and GAC each and that doesn't even dent it.Better since (@siggy ) I got home and my tank is ACTUALLY looking better. Some of the algae tufts that were still around are mostly gone and dinos look much better today. Will have to wait till tomorrow and see if they are actually receding or not...
