That is the AquaFuge PS - Large. Or at least that is what it was originally designed as. CPR Aquatic has upgraded the production to the AquaFuge2 PS systems, but china is still selling off the originals.
I have that exact HOB
fuge/skimmer that I was using on my 30 gal
. I have set it up 1 other time for a coral holding tank. All in all I think that is a great option for a system that cannot take a sump. It took my trates from around 80 to 0 in short order with a chaeto ball in there with some rock rubble.
There were a couple minor quality issues (it was slightly angled and the collection cup holding screw is, screwy. I filed the hanger so it was perfectly level (until I moved the tank and found the floor was slightly off, shouldn't have bothered) and I used a small wooden wedge to hold the cup at the right height.
All in all, I highly recommend the knock off versions as the minor faults are not worth the big bucks for the original version.
