I think that I'm starting too many question threads so I want to make this my only one...
My first question:
Should I take out the sponge cartridge from my two HOBs and fill them up completely with bio rings? Or should I keep the sponges for mechanical filtration?
And should I bury my bio balls under the substrate? Or will this be inefficient?
And also, will a refugium of 5 gallons be a waste of time for a 10 gal tank?
