Hi, I am setting up a 77gal. fish only tank. I oringinally have a Eheim2213 for my old 33gal, and I get a Magnum350 2nd hand with the 77gal tank. I want to for a sump, but its just too expensive for me now since u need a pump, overflow(my tank is not drilled), etc. I also have a Seaclone skimmer. I just want to see is it OK to run only the 2 canister and what material should I put in the canister, thanks a lot guys.
