I got my the other day been running on my 40B for 4 days now.
When I first got it, it was wet inside I guess they test run it before they shipped it out.
The o-ring and inside on the side was oily. Filter didn't come with any carbon or bio ball.
It did came with 3 white floss pad.
So far so good this filter is like a ninja I can't hear a thing sometime I wonder if this filter is working/on or not. Lol I must say the flow suck at 200+ gph this thing is weak.
If I was to guess the flow rate on this filter I would say about 145+.
This filter will be nice if there a carry handle so you can pick it up.
Here my media set up.
Bottom: ton of floss
Middle: floss, bio ball
Top: bio ball, biomax.
The skimmer on this thing doesn't work for me since the water line is high.
