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.
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?
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:
The bottom of the output on the 110ext skimmer is approximately 9.5” tall.
As long as the water is below the output of the skimmer and above the intake it will work well!
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.
That would be just fine :-)
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 systems volume. 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.

This thing is a beast By David on 5/2/2017David would recommend this product to a friendThis is my third skimmer since I started the hobby but first recirc. let me tell you I will always use recirc skimmers. This thing is very easy to tune... VERY easy. It does a far better job producing skimmate than my internal skimmers ever did. fantastic amount of consistent foam regardless of water level in my sump. love it. Had a challenge plumbing it but they included a metric to imperial converter that helped quite a bit. anyway... I highly recommend.
One quick note... I did have a bad impeller at first but customer service got me a replacement within 48 hours and it has worked 100% ever since. Love it.
Simply The Best By Fahid on 4/21/2016Fahid would recommend this product to a friendI have used a Reef Octopus skimmer for years. I had my original one begin to leak after 8+ years of usage and decided to upgrade to this new version. The new pumps are much quieter and it only took 4 days to break in. The new valve system is super easy to control and adjust. Simply the best skimmer you can purchase based on price and quality
Poor materials By 70GRimless on 2/13/201670GRimless wouldn't recommend this product to a friendFirst off, be aware you will probably need a hacksaw for cutting METRIC pvc piping, there is NO METRIC pvc piping at your local hardware store so you are stuck with this red piping that comes provided. Also the image is misleading... the pump doesn't touch the ground, it hangs. The union arm between the external pump and skimmer leaks. They even sent me a 2nd unit because the first flooded my floor and this one still leaks. If you buy this junk be prepared for a long headache during installation. EPOXY for those unions might slow the leak but the leak will persist and find some way of dripping.
Great Skimmer By Sidewinder on 4/20/2015Sidewinder would recommend this product to a friendSo far its been running around 12 days and is pulling some nice dark skim. The skimmer itself is very good quality runs super quite and was easy to put together. The only complaints I read about was about the plastic tubing. Saying it is hard to cut without smashing the tubing and that the tubing did not fit together tight. Also that the tubing is metric. First I found the tubing easy to cut with a hacksaw. I also glued the pvc with pvc glue but did not find the tubing to fit lose at all. The pipe should be guled if using external! I am using this externally but left the pipe unglued at the last bend for cleaning b/c its over my tank if it leaks. But it has not leaked! And if needed there is 2 different size metric to standard adapters included. Im very impressed with this skimmer and would recommend it to anyone looking for a inexpensive external protein skimmer
This skimmer is Great By Reef Lover on 1/21/2015Reef Lover would recommend this product to a friendGreat skimmer is great. Work as it supposed to. For everyone complaining about loose parts, there is a provided metric conversion fitting for a reason. The provided parts fit perfectly and can be extended by using normal hardware store pipe and fittings using the metric conversion fitting.
excellent skimmer!!! By Robert on 3/16/2014Robert would recommend this product to a friendThis skimmer is great. This is the third reef octopus skimmer I own and once again they hit the mark. Now if any of you are wondering why the pipes and fittings that come with the skimmer are lose when you put it together is because they are supposed to be glued together. That is the whole purpose of having a recirculating skimmer. If you didn't know that then you probably shouldn't be buying this product. Once again excellent skimmer not a single bad thing I can say about this skimmer. Thumbs up!!!!!
Odd pipe fitting, great skimmer By Crystal on 12/29/2013Crystal would recommend this product to a friendThe pipes don't fit together as snug as regular schedule 40/80 pvc. This is a minor pain when setting it up because it tends to fall apart while you are attempting to get the pieces in place before gluing them. You do need a thicker application of glue than normal. I'm slightly worried about that long term as saltwater slowly eats away at the glue. If you've ever taken down a tank that has been up for 5+ years, and you give the fittings a good whack they'll come apart because of this, even though the pipes aren't leaking beforehand.
As far as skimming, it works like a champ.
Very difficult to set up. By Lady A on 6/24/2013Lady A would recommend this product to a friendFirst, this is an external skimmer. I bought based on the fact it said it could be used either in or out of my sump. So after rearranging my wires to make room it barely fit. This is a skimmer that requires you to have a PVC cutter, PVC glue and Teflon tape. The pipes are loose and you have to use a lot of PVC glue to prevent leaks. Also I had to Teflon tape all the places where I had an o ring. That said it looks like and awesome skimmer and will see how it does after a few days.
Works Great By skimmer user on 4/3/2013skimmer user would recommend this product to a friendThe pipe fittings were a little loose, but nothing a generous application of PVC cement couldn't fix. Plastic pipe was thin walled and a bit challenging to cut since my normal cutter was squashing the pipe instead of cutting it. Assembly was easy although the directions were nothing to write home about. Was producing wet foam within 2 hours and good skimmate by the next day. Has been pulling tons of crap out of my system. Was able to install behind my refugium since there was no room in the sump.
High quality; easy to fine tune By David on 2/28/2013David would recommend this product to a friendI got this because recirculating skimmers do not depend on the water level of a sump and my sump is a regular 20g aquarium with no partitions. It is perfect. Very easy to fine tune and efficient. skimmate globs in 2 days. It does require some glueing/assembly and it's a bit large. I'm not really sure where they got the 4" from.
Easy to install! By Plumber on 2/21/2013Plumber would recommend this product to a friendThe exit return is long so you can cut it to length using virtually any cutting tool short of nail clippers. The parts fit together loosely because they are meant to be glued together once everything is fit to your tank. That's what you do with PVC.
great upgrade By James on 2/16/2013James would recommend this product to a friendI upgraded to this from a nw110 when I installed a new fuge in my sump and needed to install the skimmer internally. Since it is more or less the same model I expected similar performance but this is at least twice as effective. The recirculating design produces a much thicker foam. The return pipe that came with it wasn't long enough for my install but it did come with a metric conversion fitting so I could use my own PVC.
