This is for my 10G Reef, with around 13lbs LR
I recently picked up a new HoB
and have used up the slot cartridge thingies which came with it.
In the 4 'compartments' it has I'm now running a bag of Purigen, Carbon and GFO
Basically, I hate having empty space which could be made useful.
So what could I stuff in there to fill it up?
I was thinking of some extra bio-media like ceramic rings or lava rock rubble.
What do we think?
