View Full Version : Octopus NW-150

06/08/2008, 04:34 PM
I just bought an octopus nw150 and wondering how you get this thing working. Gave it a vinegar bath. I pluged it in and water rises about 1/4 up the main chamber and then does nothing. Doesn't seem like the pump can get the water to near the collection cup. I see some octopus w/ two pumps am i missing somthing. The site has no manual and the lfs i bought it from sold the unit itself no box or manual.

Is it a re-circulating skimmer? If not then it only needs one pump.

06/08/2008, 06:21 PM
no i dont think its a recirculating skimmer it says pump skimmer.

Seems like the pump isnt doing its thing then, huh. When you tested it did you use salt water? Skimmers dont work right in fresh. Has it been modified in any way you can tell?

don't think it has been modded its In my sump right now.

is the pump bad?
it pumps but not much

Could you take a pic? of it running. The pump may not be pulling air, you may have your standpipe very low....etc.

here you go.

why is the water so dirty?

06/08/2008, 07:54 PM
Yea, that was my first thought. It doesn't look like the pump is working at all. I'd pull the pump, pull off the volute cover and see if the impeller is connected correctly, meaning the shaft and all is on there right. Then make sure the venturi line isn't clogged. if those two things don't work, then contact the dealer who sold it to you.

i dunno ever since i put cheato in my sump water turned green. Sump water is green while the main tank is cloudy white. Im thinknig its bacteria bloom. Its been like that for 2 days now. did a 25% water change and got cloudy again.

ok went to the lfs and worker looked at it. put it in a rock curing tank and it didn't work. Water didn't travel up. He took out the front of the pump to see if the propellers where spinning and they were. put the front back on and couldn't figure out why it wasn't working. He blew into the white flexible tubing and then all of a sudden it started working. I took it home it started the skimmer up and it wouldn't work until i blew into the tube. So to get this NW150 to work you got to blow into the flexible tubing. I don't see how any new person could know that. Not even the worker knew about this. I wish the company would include a manual post or post it on their website. its working and now i have a skimmer so i am happy.

the pump was probably cavitating... had a big air bubble in the pump that would not allow for the pump to function

06/09/2008, 05:54 PM
i have the same skimmer had no problems with it .

06/09/2008, 06:33 PM
do you really thing blowing into the air tube is nessicary and that its the company fault for not saying that?

Something was jammed in it probably.

06/09/2008, 06:43 PM
I've never had to blow in mine, even slightly modded. Something doesn't sound right. Sounds like there's something binding the impeller.

06/09/2008, 08:19 PM
Having to blow into it to get it to work is not normal, I have the same skimmer, plugged it in and it started going.

06/09/2008, 08:20 PM
Mine started doing that. So I switched my pump, and hasn't happened since. Something is wrong with the pump. Marine Solutions swapped mine no problems.

FYI I just got a new NW-150 and had to blow into the pump to get it working as well. I heard that Octopus redesigned their pumps so maybe it's related to the new pump? I will talk to the LFS where I got the pump anyway.

I have to blow into the air line on my new style octo NW110. It will stick after I unplug it, it is mesh modded though.

I have the same skimmer, I bought it because the price was resonable for my tank size. It was plug and play no problems at all. Tons of micro bubbles.

09/15/2008, 08:42 PM
I tried taking the impeller out and re-installing it, but every time it needs a blow-start! The LFS has a new one coming though. Weird...

I got the new pump for my NW-150 today. Plugged it in and same thing. Making noise, but no pumping. Blew in the airline and it started up. Am I that unlucky?
