Freshwater filters

[krispywhite]

Hi, I am running a fx4 on a 100 gallon tank, all tests are great no problems, I am keeping South American cichlids tank well stocked with fish from 2 - 8 inches, before all the fish get big, I am thinking of running another fx4 as well ( fx6 is to high for cabinet ) or maybe setting up a sump filter to replace the fx4, any advice or suggestions please, thanks I am a new member to the forum

I don't see why you couldn't run two FX4's.

For that size tank I am a big fan of sumps. Do a great job cleaning and aerating and are easy to clean themselves.
