GFO reactor serup

[rockdiver]

So I have a BRS single reactor and I need to run some gfo since I was slacking on things all summer and it all finally caught up with me.
Anyway when putting in the gfo do you put a sponge at the bottom and the very top or just at the top ? Can't really find any info on that.
I know you want a nice but not crazy tumble.
Then also I was going to have the water come out into a filter sock is that a good idea or not needed.
Thanks

One on top, one on bottom. Good idea on the filter sock. Will catch any GFO fines.

Maybe mix with gac if you also run that to prevent gfo clumping.

Thanks guys !
