Product Questions

Would this work with a mixed reef heavy bioload 125 gallon?
Question by: Brenden on Jun 8, 2016 8:07:00 PM
This skimmer could work on a lighter bio-load 125. However with a heaver load we recommend a larger skimmer closer to 200 Gallon rated bio-load.

Would this work on a 90 gallon mixed reef with a heavy bioload?
Question by: TJ on Apr 19, 2016 6:57:00 PM
Great question!
This will work well with a 90 gallon tank. Feel free to let us know if you have any further questions!

  • I'd buy another By Michael on 2/11/2017

    Bought this based off a recommendation from a friend, couldn't be happier. Ran it for 2 weeks wide open to break the pump in. Raised it up about 3.5 inch and it's doing some serious work. I'd buy another no question.

    Works great
  • Best Bang For your Buck By Ty on 9/14/2016

    I do aquaculture for a living at a research institute. I have three skimmers, the Skimz Monster 252 external, the Vertex Omega 180i, and this one. The Classic 152-S is simple, cheap and effective. Not as sturdy as the Omega 180i but the gate valve makes it much easier to tune than the vertex. If I had a tank at home, this is what I would use.
  • Not good By Jason on 3/8/2016

    Simply doesn't work, I have tried everything, raising, lowering, waiting, adjusting, tweaking, waiting. Nothing helps, maybe mine is defective. ... I don't know, I'm ready to throw it in the street.
