FX5 or sump for 75gallon tank

  • We are currently upgrading MFK. thanks! -neo
I've already got a bunch of scrubbies for it, but I've been thinking of changing the media a little. Last time I used all scrubbies, but was thinking to use ceramic rings submerged in the water and scrubbies above the water line..I always hear/see people talking how scrubbies don't do well submerged in water.
 
Mechanical filtration is not nessecary in any setup. It's only for our viewing pleasure and plays no part in the nitrogen cycle. No matter if the waste is free floating or trapped in a sock or pad, it's still in the system. That being said you can get socks as fine as you want. There is also a difference between a sump and wet dry, so cheap pot scrubbies can be used or eheim media can be used.

Sump all the way here, although I will agree that an fx5 can handle a 75g w ease, sumps are where it's at!
 
I'll probably hook up my sump to this one as I'll be leaving it as bare bottom and can siphon out all the crap and just use the sump for biological filtration since I may be using it as a temporary grow out for a catfish! Because I plan on building a larger tank/pond in the near future! Well as long as my new job comes through that is and I'll know soon enough about that ;)
 
I would go with the fluval.
 
I would go with the FX5.. I have both on my 300 and to be honest the sump drives me nuts.. I'm sooo tired of having to clean my filter socks/mats every other damn day.. :irked: The only reason i leave my sump running is because my tank is drilled with overflows, and i also have a fluidized bed filter running in it.
 
Do both. That's what I am doing for my 75G Tropheus tank. I have a 30G sump but I found the mech filtration lacking since it skims the surface, so I'm adding a Eheim 2080 to it!
 
^^^ you need more in tank flow. There is absolutely no reason to run an fx5 and a 30g sump on a 75 unless you want to waste electricity. Either can handle the job just fine but a sump allows for a cleaner look and more flexibility
