In my case, it worked too well. Even with 1 torpedo on my 215, it worked too well. For a FO tank, I wouldn't hesitate.
I had red slime on my rocks and gravel and not it just a white film and falling away from the rock and gravel. They are all dead. My coral seem to enjoy the cloudy water. They seem to be eating the stuff. I think it is RN bacteria. They grow on my rock and tank glass. I test the water and the alk/cal is a little low. I going to let it run like this for a few days to make sure the red slime bacteria are all gone then turn off the second pump.

My skimmer is full of this stuff and it is not dust. My skimmer is working overtime. I get a full cup of white stuff every day.
