As per my discussion with Coralvue, the air draw goes up and the wattage goes down when you lower the water level. So based on your amperage readings I'd say your running a water level at the upper end of skimmers operating range.

I'll probably be buying one to try out before I jump in head first and buy 6!

here is the video of this skimmer and the exchange I had with Coralvue in the comments

What is the device you used when finding out the watteage used called.
I would like to see what the vertex omega pulls but it uses the same pump so it will likely be the same

User Spedley used his apex EB8 to read the amperage draw of the unit, he measured .6 amps, which is approx 72 watts

a kill-a-watt is more accurate but costs like 30 dollars

So I dug deeper. here is a statement directly from the top

"Please understand that the readings will very pump to pump but they will be within the ballpark listed. If you read the pumps with a Kill-a-watt you will see that the numbers are at or near the listed number on our website. Of course there are several factors that can effect the air and water draw which has an impact on the pumps wattage and power factor. Water (DOC and salinity), altitude. sump water depth as well as inner water level within the skimmer will effect air, water and wattage.

I have a K2-200 with a Sicce 1000 and a K2-160 with a Sicce 600 running here and tested them this morning with a kill-a-watt
The k2-200 is reading around 20-26watts while the K2-160 is drawing around 18-20watts depending on the water level within the skimmer.

Air draw has a big impact on the wattage draw of a given pump. Sicce does not provide a venturi for their skimmer pumps and the design of skimmers very thus the performance of their pumps will very by skimmer manufacturer. Hope this helps. Let me know if you have any further questions."

Theokie, you are correct. I'm running mine in about 9.5" of water. The manual recommends 8"-10" I think. The water level of my skimmer compartment of my sump is fixed at 9.5" and I don't have the overhead to raise it more than half an inch. This just might be the way it is for me.

I'm going to wait and see how things are in a couple of weeks. I've only had it in my system for four days. Perhaps when it's broken in and not thrashing so hard the wattage will go down. Sometime before then I'll order a Kill A Watt device because this has got my OCD working and I need. Answers. Now.

Ray, thanks a million for going out of your way to get some information right from the top!

Yes, it appears that as the pump breaks in that power consumption decreases. I just measured 0.4 amps, which is 48 watts. So definitely improving over time.

Thanks for the update!
