Just curious, I'm in the market for another skimmer, and I've been looking at the Octopus DNW-200... I see they are rated for 200 gallons on Premiums site.. other sites, rated for 300... are these realistic ratings?

Also, are these pretty much the same as the Pacific Coast Imports RPS-3000's?

Seeing the size of the skimmer, If I decide to go with them, since they are cheaply priced.. I'll probably do a mesh-mod, and possibly add another recirc. pump...

Any opinions?

I currently have a 120g tank, low-med. stocked... probably soon med. stocked.. total system volume around 175 gallons with sump, and fuge.....

just use Euroreefs. For example the NW-200 is a copy of the RS180 and has the exact same demensions (8" body, 24" tall, same footprint). Euroreefs ratings are accurate so the Octo should be good for up to 180g. If its not quite an equal to the euro reef knock off 10-20gallons which would still make it good to at least 160g

I wouldn't say the ER ratings are that accurate...every company inflates their ratings some, except BK IMO

I would not put an unmodded DNW200 on a 175 gal system...mod it and it will do fine for your tank.

the Octopus and Pacific Coast are the same skimmers.

I just oinstalled my new PCI PS-3000 on my newly set up 180 gallon that has about 240 total gallons... all I have in there so far is sand, and some rock I had been cooking for over a year and 3 new rocks from the LFS... this thing is already pulling out the nastiest skimmate I have ever seen. I have not modded it yet either... going to wait and see how it performs when I transfer all of my livestock over from the 29 I have had running for a couple of years now. for what its worth....

I'm sorry, but thats completely false. If the Octopus is a copy of the RS-180, then pretty much every skimmer on the market is a copy of the Deltecs made 50 years ago. Theyre not all that similar, other than the height/diameter.

The NW200 also came out BEFORE the RS180, so its funny how its a copy.

Can a NW200 handle a 200g tank? I think so. Have I tried it?no.

Rich... have you modded your PS-3000? How hard was it to do if you did???

Meshmodding and fixing the venturi is easy.

Mine is recirculating and using a different pump, so I'm not sure I'd even call it a PS3000 anymore.

Actually I was looking into the Octopus DNW-200 (recirc)... but still, If I compare it to the Euroreef... RC-180,, the Octo is 5 inches taller... not sure about the neck diameter... but looking at prices... Octo DNW200 - $380,,, Euro-RC-180 - $840... big difference there!!

I'm actually wanting a recirculating skimmer... My other option was an Orca skimmer... but... Just trying to justify the price... I don't mind doing some minor modding...

But, I noticed the NW200 is rated at 175, and the DNW200 is rated at 200... only a 25 gallon difference for a recirculating model?

All I know is I upgraded tanks, without upgrading skimmers, and I'm still stuck with a Coralife CSS220... ya.. it's just not cutting it....

What kind of mods would you recommend? Could the body/neck diameter handle another recirc pump? or are you just talking mesh-modding it?

the neck will handle another unmodded OTP3000 pump...but there would be LOTS of turbulence. Your best bet is to meshmod the pump, and slightly open all of the plumbing on the skimmer body.

stop being so gun ho all the time. I used the RS-180 because that is what euroreef has out NOW and the demensions are the same. I am aware the RS series hasn't been around that long. would it make you happy if I said CS8-2? Minus the pump they are very simular in general design and the size simularity and both sharing the same general design is the precise reason I suggested it. If recircing doesn't change euroreef's capacity rating of same size skimmers in brand the differences between the octo and euroreef sure shouldn't be reason not to use euroreefs capacity ratings if you believe they are much more accurate than octopus and alot of other manufacturers as I do.

Sorry about that I misread which model (somehow missed the D). the DNW-200 is most definately suitable for your size tank and if you have a coralife 220 currently you should be THRILLED with it even unmodded (though there is no reason not to do a $5 mesh mod).

can someone point me to how to mod these skimmers and explain to me WHY one would want to do it...

thanks!

Be careful modding your skimmer, I ruined one pump (mesh mod) and one venturi (drill mod) modding mine. I am now back completely to stock.

Once drilled I could not put the venturi back to stock operation, no matter what I tried.

That being said plenty of folks have had great luck modding.

As far as why, mesh mod pulls in more air and makes finer bubbles, venturi mod allows the mesh mod to pull in more air.
