Eheim canister filter (additionally) for my reef tank
I have a 160 g. capacity Eheim canister filter at my disposal that I can use on my 148 g reef tank along with the protein skimmer. Question: is this ok to do and if so, should it only be used with a carbon media? And if so, set up in the in/out lines within the sump, or the tank itself.......advise much appreciated!
