I've been using an Emperor 400 HOB filter on my main tank, almost since I started it up. I use it for additional mechanical filtration, as well as a way to introduce carbon into the system. however, I DO NOT use the bio-wheels, they are removed. My water is always nice and clear.
Now, I have my sump, a DIY ER skimmer, and a filter sock on the end of my overflow hose.
Am I better off without the 400? I seem to always have a nitrate level hovering around 10-15, and my zoos aren't too happy, not opening all the way. The other livestock seems ok, but my nano has much happier livestock with just a skimmer and a small Aqua Clear.
Also, the 400 has a lot of algae and slime growing on the return chutes.
What do you think?
