Emperer Filters....

I not a big fan of those.The biowheels tend to get salt creep and stop turning.Also the biowheels can become a nitrate trap.
 
I used to run 2 of the emperor 400s on my 55.There like any thing else,you have to clean and maintain them.But as long you keep em up,there a pretty good filter.
 
I am running a modified whisper HOB filter on the 90 reef. It works great and needs to be cleaned only once a week. I don't like the biowheels. Just my :twocents:
