Hello, I have a small tank with a hang on filter. I have my mechanical and bio filters along with a carbon bag in the filter. Could I put dinner GFO in a bag and place in my filter? Will the water running over it be enough? Can it even be used this way?
I'm still learning and trying to get everything stable for my tank.
Thank you!
Kristie
