Eheim 2217 filtration media layout
I am changing my media up for my new tank:
From bottom up (all Eheim brand)
Bio media balls (Eheim substrat pro)
Carbon (to be replaced with Purigen once cycled)
Is this ideal? Is the mech even worth having in there? Basically Iím taking out the Eheim mech (which I imagine doesnít do anything) and replacing with an extra fine pad and more subtract pro capacity.
