2 or 3 canister filters?

[threeguns]

How many people run 2 or 3 filters in their set up? 1 caninister for bio, 1 for mech, 1 for as a water polisher and why...

i run 2 Fx5s on my 330. each has polishers on the bottom and bio in the top two racks. Eventually i might get another Fx5 on the tank but for now its doing just fine. I did this because it was the easiest thing to setup. quick and simple. And i knew it would work. ive never made a sump and didnt want to risk drilling something wrong

more is better

I run one that's mainly for bio, one for mostly mechanical/water polishing.

I believe water polishing is a form of mech

 

[Redearsunfish]

I run as many filters on each tank that is physically and fiscally possible. Just me..

i run 2 fluval FX5's on a 120g... works very well
run bio/mech in both, clean them each out every 3 months or so alterenately

I do not see a need to run 3 to accomplish seperate task. I run the Eheim 2250, 2262 along with the FX5 on my 200 but I do not have them performing seperate task.

+1 I run 2 eheims and a fluval on my 135 but I don't see the need to split filtration. I was under the assumption that each filter ran best with a stage of each, so as to slow water flow enugh to build beneficial bacteria, and polish water befor it gota back into the tank. I don't really see a benefit in running one for each just my opinion
