I recently set up a new 75 gal aquarium, hopes for a discus group when I get it all ready. I've added some plants to the tank now and have Coralife Fixture LED 48 inch, along with a strip light the tank came with. I have a AquaTop CF-400-UV Canister Filter but am not sure if I need more 'water movement' ? It seems manufacturers often under-rate filter performances. The day after adding plants, moss etc, I still have some floaters in the tank and think I need more filtration to have that perfect water for my eventual plan of discus. I am thinking of adding yet, another filter, maybe an Aquaclear 110 HOB filter? Any input . Do others run more than (canister) one filter / combinations etc. Thanks in advance.
