Quick Overview

Sumps are a great addition to any fresh or saltwater tank. From adding additional water volume to area for heaters, reactors, probes, and any other life support equipment you may want to add. Many tanks are already drilled or can be drilled for a sump to be added.

Skimz Sumps are by far one of the best sumps for the money and packed with features all reefers will value.

  • Dimensions: 34” L x 15” W x 15” H

  • Skimmer Chamber: 13” x 14”

  • Refugium Chamber: 5" x 14"

  • Return Chamber: 8” x 14”

  • Approximate Water Volume: 30 gallons

  • Top Off Volume: 2.4 gallons

  • Skimmer Chamber Water Level: Adjustable from 7” – 9” with Level-O-Matic

We suggest choosing the largest sump that you can fit in the space allowed.


Full Details

The features of the Skimz Sumpro series have been designed with the advanced reefer in mind, many of which you will normally only find on expensive, high end sumps. All Skimz sumps include integrated probe holders, filter socks, tube holders and an adjustable skimmer chamber. With a super clear front acrylic window allowing you see your equipment without any distortion and all other sides are white to keep things bright and super sharp looking.


DuoFlo Sock Chamber

With the importance of crystal clear water every Skimz sump comes with a DuoFlo tiered filter sock system. The system incorporates two filter socks of different lengths in a series allowing for fewer changes of both filter socks, and the ability to install a progressive micron system of filter socks.



Allows quick and steady adjustments of the water height in the skimmer chamber by controlling an adjustable baffle. There are no thumb screws to mess around with like many of the competitors and your hands will stay dry when adjusting the baffle allowing your choice of skimmer to perform at its prime level.


Probe Holders

Each Skimz Sumpro Sump comes with 4 integrated probe holders that will accompany any type of probe up to ½” diameter.


Dosing Tubes

Dosing tubes can always be a source of clutter and headache to keep looking clean and not a tangled mess. Every Skimz Sumpro sump comes with 4 dosing tubes letting you dose anything you want from trace element solutions, calcium reactor effluent, nitrate reactors, or anything else that uses standard 3/16” tubing.


Top-Off Chamber

Select Skimz models even include and integrated top-off chamber to house freshwater, just add an ATO unit and your set. The compartment that is dedicated for fresh top off water even includes a perfectly fitting lid that includes notches allowing the ATO's power cord and tubing to sneak through without modification.


Refugium Chamber

The Refugium Chamber on select models of the Sumpro’s will allow you to grow beneficial macroalgae to help combat nutrient build up as well as house zooplanktons like copepods and amphipods. The Refugium section does have white acrylic baffles keeping the light in the refugium and from spilling out onto other equipment.

  • good sump - poor service By leszekpmd on 9/18/2017

    trying to get replacement for original SKIMZ El-M300 Filter Sock and EL-S300 Filter Sock but they are listed on BRS web site as "RETIRED".
  • Its OK after some mods By Jesse on 8/6/2017

    I purchased this sump mainly because of the size of the skimmer chamber and the way the 2 intakes were made. I plumbed my beananimal with the suggested 1.5" pipes. I did not want to reduce it as it goes into the sump for obvious reason. Unfortunately they do not provide a fitting for 1.5" so my pipes just hang thru the holes. What I didn't realize when purchasing, is that there is no bubble trap. That was the first issue with the sump that required me to make a slide in bubble trap. The adjustable outlet into the return chamber is just another bubble maker when you have any decent flow going thru the sump. Reason being is the small window that you are pushing all of that flow thru. The little guard with the course sponge in the bottom is absolutely worthless. The next issue is minor but still annoying. The probe holder is in the back area of the refugium chamber. After a couple months of use, it's completely covered in stagnant water and algae. There is not enough flow in this corner to keep the area clean. The main pluses of the sump are the ATO resevoir and the large skimmer chamber. Also, the sump is very well made. Overall I am happy with the sump but not for the price that I paid. A bubble trap would have probably made this a great sump. As is, it's just ok...
  • Love the sump By Jamesand on 1/22/2017

    Very quiet sump and easy to set up and use. Great foot print for all chambers.
  • Excellent Product By FishyDoug on 12/16/2016

    With plenty of volume and room for accessories, this sump gives you everything you need. The only drawback is that the existing filter sock holes do not hold industry standard sized sock retainers (the plastic piece at the top). I will be investigating a way to enlarge the hole as there is no reason to require you to order the socks exclusively from Skimz or "special" sizes that fit.
  • Great Value By Nick on 6/12/2016

    I recently purchased this sump and I was bit concerned as this is a new product with no reviews to be found online. I'm very happy I took the chance and ordered this sump from BRS. The quality and features are well worth the price.

Is the water volume listed if the sump was full to the brim or the additional water volume added to the system when running?
Question by: Trevor Frick on Jan 10, 2017 5:15:00 PM
Great question! The water volume listed is the total water volume available when the sump is full. It can hold 30gal of water at max capacity. :-)
