Bderick67;5155407; said:You can also effectively filter and clean the tank with a 12 dollar hydro IV sponge and a vacuum hose. So this makes anything over 30 bucks unnecessary. Your power head will not filter the tank if the the FX5 should fail. The powerhead will not filter out any particles, but only blow it around. Also having two filters makes for a more stable biofilter, as you can clean one while the other is not disturbed. I would not run a 110g tank on a single filter. Is 2 FX5s overkill, yes but not to the point that it is stupid. Maybe two XP3s would make more sense, IDK may just be up to individual preference.
Two FX5s on a 110 is overkill to the point where it's stupid, IMO. Like I suggested before, one fx5 and some additional mechanical filtration would be more than enough. The OP has complained in the past about money issues with his setups, that money for the second FX5 could be much more smartly spent. If you have money to burn, go ahead. But why not buy a bigger tank? 110 is still only 4 feet.
