25G AIO tank.......6 weeks into cycling....
Does running activated carbon in chamber 1 rear sump have positive or negative effects on starting a new aquarium?
I put the carbon pack that came with the tank and the pack of GFO
that came with the tank in it on startup.........did I F it up?
I took the GFO
out the other day after reading it may be bad for a startup.......
I got new activated carbon but wondering now should I replace it? take the old out?
