    I have been running this on my 150 gal reef tank for over a year now and its been great. I have a biopellet reactor (Aquamaxx XL) plumbed in-line to the skimmer and the flow rates match up well. Easy to adjust and getting substantially and consonantly more nasty skimate. It also fit under my tank and is still easy to access to clean. good build quality as well. Works well, I recommend it.
  • So far so good By Nathan on 6/20/2016

    I should have bought a new skimmer a long time ago. This was easy to setup and had a very predictable and quick break in period. The best part is it is easy to adjust. This thing is pulling all kinds of nasty stuff out of my water.
  • Great skimmer! By Jeremy on 1/27/2016

    I debated quite a while on a skimmer upgrade. I am glad I purchased this unit. It works wonderfully. It took about a week to break in but tuned in well! It is super quiet and well made. I like the versatility of the external option although I have it in a sump. This way the feed cycle and variable maintenance will not effect the output of skimate. Love it!
  • nice and very good quality By brad on 7/6/2015

    Very good quality parts and fittings. Perfect squatty height for limited space. Pulls like crazy. quiet...also will go internal. Very happy with it,but could use more comprehensive instructions.

Product Questions

This is actually an "external" skimmer, which can be run outside the sump, correct? However, based on the description and answers to previous questions it can also be run internally. When run inside the sump with it's own pump, the depth of the water in the skimmer section of the sump does not actually affect the performance of the skimmer, other than with regard to the outlet, correct?
Question by: Doug Brewer on Dec 2, 2016 8:19:00 AM
You are absolutely correct! Check out our BRS 160 and the 52 Weeks of Reefing series, where we utilize a Skimz External skimmer within the sump. :-)
Answer by: Randy (Admin) on Dec 2, 2016 8:51:00 AM
Is the Skimz Monzter SM202 External Protein Skimmer discontinued? The reason I ask is it have been out of stock for a long time.
Question by: Channing Jordan on Jun 8, 2017 12:56:00 PM
I'm not showing the SM202 as discontinued, but it does look like there may be some issues from the supplier as our last order of them did not come in. Hopefully we should be able to get some more from Skimz in the near future!

Happy reefing!

Looking at buying SM202.
1) What feed pump would you suggest
2) Can the feed pump and the return be in the same chamber of water
Question by: David on Aug 1, 2014 6:28:00 AM
1) My preference would be the Sicce Syncra Silent 2.0, though any pump around 500gph should do the trick.
2) That isn't any issue at all.

Is there an max water hight that this skimmer can operate in?
Question by: Phillip Piddington on Jul 6, 2016 7:44:00 PM
The SM202 can run in up to about 11” of water. We would suggest no more than 10” just to be safe as the output of the skimmer will need to be able to freely drain back into the sump which sits at about 12” tall. If you have any other questions just let us know.
Answer by: Charlie (Admin) on Jul 7, 2016 11:09:00 AM
1. What is the output height inches for the Skimz Monzter SM202? Is there a way to extend the output height?
2. I see that the total height is 22.83”. My cabinet is 24.5" will I need more then an inch and a half clearance?
3. I have a 150 gallon reef tank that has been running with a small outdated skimmer for almost 20 years - would moving up to the SM252 be overkill for this size tank?
Question by: David on Aug 27, 2014 8:57:00 AM
Hi David,

The bottom of the return pipe sits at 10 1/4" inches. The absolute minimum height to allow you to remove the cup would be about 23 3/4". 24" would be comfortable but a little tight so 24 1/2" would be fine. Just make sure you have the room to clear any other obstacles to actually get the cup out from under the cabinet once removed.

I think the SM202 would be plenty of skimmer for your system and you are going to be amazed at what your old one wasn't pulling out! The SM252 is probably going to be overkill unless you have a ton of fish and feed heavily.

I hope this helps!
Have a great day :)
