Hello MFK members, ive been fishkeeping for a while now so i think im ready to get a bigger tank, I was planning on starting a 6 foot long 125 gal with a jardini arowana and maybe adding an oscar or two down the road.. my question is would a 2 sponge filters rated for 125 gallons work for the tank or should i have a canister filter on top of the sponges also? Thank you anyone who can help
