I have 2 x Eheim 2028 canister filters (only filters) running my 170G freshwater tank. The spray bars are positioned so most of the fish waste is sweep to one corner of the tank. I am considering removing the all of the Ehfi Mech on the one canister (opposite end fish waste collection) and replacing it with only Ehfisubstrat to provide more room for BB. I would still use the blue pad. THe other 2028 filter would be left as is with the Ehfi Mech.
Is this a good idea?
Thanks.
