  • Not exactly quiet By Merv 49 on 8/6/2017

    This is my first time buying or using a skimmer. I don't have anything to compare the noise level to but i would not call it quiet. There is a constant hum that isn't very annoying but you know it's running for sure.
  • So far so good By dannyb on 8/13/2016

    Have only had this skimmer for a few weeks but the break in has gone great. The build quality is fantastic, the skimmer itself is beautiful and could be treated as artwork if not covered in fish poo :D Pretty easy to tune, absolutely no noise, and our nitrates are on a steady downfall. Cannot complain. The only thing I haven't really figured out is how much airflow to allow it to use.

Product Questions

Just wondering what is the wattage on this skimmer, as the description says 22watt but the sticker on the pump says 76watt? I'm seeing a trend of the newer skimmers making claims that put them in the 900-1000 lph air draw, but then claiming only 20 ish watts.... only to see people measuring the actual amp draw and seeing that they are in the 60-70 watt range just like all the other skimmer pumps.
Question by: Eric Leahy on Apr 3, 2016 6:24:00 PM
Great question!
The wattage difference stems from what material the pump is pushing. When used as a skimmer pump with volute the pump will draw between 18-22 watts. We were actually able to test this with our watt meter. When the pump is drawing only water the wattage increase to 50-60 watts. When used as a standard skimmer the wattage will be 18-22. Feel free to let us know if you have any further questions!

Hey I am interested in either the octa or the dc oval with a heavy bioload rating for around 200ish gallon tank. I noticed in the related item category for this skimmer the reef octopus auto kneck cleaner was listed... Is there a model of the reef octopus kneck cleaner that would fit the Skimz skimmer or better yet does Skimz make one?
Question by: Matt on Apr 7, 2016 3:49:00 PM
Great question!
There is not currently a neck cleaner designed for the Skimz protein skimmers. The ANC 200 may be able to be modified to work however would not be a direct fit. Feel free to let us know if you have any further questions!

I've been looking into the Skimz Octa SC205i Internal Protein Skimmer for my 70 gallon reef tank, with a net water volume of 90 gallons. I am a heavy feeder and plan to stock the tank pretty heavily as well. It will be a zeovit tank, like the BRS 160. My question is, is this skimmer an appropriate choice for my tank, if not can you suggest a better fit?
Thanks in advance!

Great question!
You will want to select the next size down for best performance the SC165 will be more than enough to keep up with your heavy biol-load. Feel free to let us know if you have any further questions!
