gfo used properly?

[LuckyReefer]

I feel like i’m not setting up my gfo reactor to work at its best potential, the flow stops after about a week or so and i feel like im just wasting both carbon and gfo. when i changed it a couple days ago the bottom was fully tumbling but the rest of the reactor was packed and not tumbling at all, and i hear its not supposed to tumble at all and or its supposed to tumble a bit i have no clue..

If you mix the gac and gfo it does not need to tumble.
The tumbling is to reduce gfo clumping, which reduces its effectivness.
