HI everyone, I am new to the the forum but have been checking it out for awhile. I recentley just purchased a 125 gallon tank with 2 rena xp3, 2 heaters, and a whole mess of lava rock. I just built a stand for it and have the tank in place. I am currentley leaning towards doing a SA cichlid tank. Do I need to run both filters to properly turn over the tank. It has a flow rate of 350 GPH. The filters did not come with any filtration media, and there are several different ones for each canister, so I am a little confused.
