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.

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 ?? 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.
