External protein skimmer powered by Aquatrance 1000 pump with an improved venturi design and pinwheel impeller. Built with high-quality acrylic. Wedge pipe output allows for more adjustment of the skimmer compared to ball valves. ½” clearance required to remove collection cup for easy cleaning.

Footprint - 10.4" x 9.25"

Height - 22.8"

Feed Pump Required - 120 to 260 gph recommended

 

The Classic 110EXT skimmer requires a feed pump to feed water to the skimmer. The recommended maximum flow rating for this skimmer is 260 GPH. These numbers are based on zero back pressure on the output plumbing. If you add 90° bends on the plumbing back to a sump you may need to back off the amount of water being feed through the skimmer. We recommend that you use a ball valve inline from your feed pump to the skimmer allowing you to control the water flow.

  • High-performance venturi air injection system
  • Modified cone neck design designed for easy transition of micro bubbles into cup
  • Requires a feed pump or plumbed from an overflow to inject water into skimmer
  • Can be in sump or external
  • Metric plumbing parts.
  • 1 year warranty on skimmer and pump

 

Note: A feed pump is required that can flow around 1.5 - 2 times the volume of the system. We suggest a pump around 150 to 250 GPH, and particularly like the VarioS 2 Controllable DC pump or Sicce Syncra Silent 2.0, we also highly recommend a gate valve to help control and fine-tune the flow of water into the skimmer from the feed pump.

Product Questions

Is there a way that I can I increase the flow rate to 300 gph?
Question by: Owen on Nov 24, 2013, 11:53 PM
Hi Owen,
You can use a faster pump and then slow that pump down manually via a ball valve or something similar. You don't want to actually run more water threw the skimmer then recommended though. That will generally lead to reduced contact time, more escaped micro bubbles, and often an overflowing skimmer.

Hi,

I want to run this completely out of water. I don't mind having a second pump. First, can I do this? Second, is there anything special that I need to do? Third, what pump should I use?

Thanks.

Great question! The beauty if external skimmers like this is that they can be used inside the tank or externally. The plumbing connections to the skimmer are included, however you may need additional plumbing parts for your particular setup requirements. We suggest a pump around 150 to 250 GPH, and particularly like the VarioS 2 Controllable DC pump or Sicce Syncra Silent 2.0, we also highly recommend a gate valve to help control and fine tune the flow of water into the skimmer from the feed pump. :-)

I dont have a sump. I use a fluval 406 canister filter. How do I run water to this skimmer from my tank and then back to the tank?
Question by: Chris Meyer on May 8, 2014, 4:12 PM
Hi Chris,
Unfortunately you can't, at least not unless you find a way to put the skimmer up higher then your tank as recirculating skimmers drain back to the tank via gravity. For a sumpless system skimmer options will be basically limited to the hang on back skimmers like the BH series skimmers from Octopus:

What is the height of bottom point of output pipe?
Question by: Alex on Jul 21, 2016, 6:48 AM
Hi Alex,
The bottom of the output on the 110ext skimmer is approximately 9.5” tall.

if I was going to put this skimmer in my sump, what depth of water should it sit in?
Question by: Chad on Apr 22, 2016, 6:07 PM
Great question!
As long as the water is below the output of the skimmer and above the intake it will work well!

What do I need to run external?
Question by: Aaron on Oct 11, 2013, 7:43 PM

Hi Aaron,
You will still need a supply pump to supply water to the skimmer but if you want to physically set the skimmer in your sump, that isn't any issue at all.

Is this model the dnw or dnwb? I believe the dnwb is external and is this the internal one? Or are they both the same?
Question by: Nicholas on Mar 26, 2014, 3:58 PM

Hi Nicholas, this particular model (the DNW110) is the DNWB series of skimmer. They are recirculating models of skimmers. Recirculating models can also be used externally if your space and equipment accommodates that, though that is just a side effect of the recirculating action of the skimmer :-)
Answer by: Bulk Reef Supply on Mar 26, 2014, 3:58 PM
The dnw110 requires a 250 gph feed pump for external but I have a 243 gph feed pump. Will that be okay?

Hi Nicholas,
That would be just fine :-)
