I own one. Pulls out the "stuff" like nobodys business. I did order a Genx needlewheel, I may make it a recirculating skimmer. Haven't decided yet.
I will mesh mod it though.
I bought this off of a friend. He had it on a 120g. The thing spit out a cup of nasty black stuff everyday with a light Bioload.
I get more of a tea color in the bucket, because all the solids seem to stay in the line and the cup.
I have 1 small Sailfin, 4 Blue green Chromis and an Engineer goby.
This is after 24hrs.
