Full Details

The Emerald series introduces several new features not found anywhere else. Some of the features of the Emerald sumps are:

  • Interchangeable plates (PAT PENDING)
  • Lid to prevent splashing
  • Adjustable water height
  • Self-adjusting foam block platform (PAT PENDING)
  • Dual platforms
  • Protein skimmer section
  • Refugium section
  • Emerald green coloring to block light and prevent unwanted algae growth in other sections


EMERALD Water Flow

Water enters the EMERALD sumps into a dedicated section where the water will then flow over into Section 1.

Section 1 where the interchangeable plate is located allowing for either filter sock or foam block mechanical filtration. This area is covered with a lid to prevent water splashing. Water then flows out the bottom of Section 1 into Section 2.

Section 2 is typically where the protein skimmer is located. Water then flows through the ‘Trigger Symbol’ cutout into Section 3.

Section 3 is the refugium section. The water then flows over the second baffle through 2 perforated platforms and under the third baffle into Section 3. The top perforated platform comes with a foam block filter and the bottom one is open to use for several different filtration methods (bag of carbon, bio balls, rubble rock, etc.).

Section 4 is the return water section back into the tank. This is where the return pump will sit.


Interchangeable Plates (PAT PENDING)

Each Emerald sump comes with two plates that can be placed into Section 1:

  • Filter Sock Plate
  • Foam Block Plate

The filter sock plate is installed when the included 100 micron filter socks are desired.

The foam block plate is perforated with holes and comes with a foam sponge block filter. The foam block plate can be used when filter socks are not desired or in the case when the filter socks need to be changed or cleaned but replacements socks are not readily available but yet mechanical filtration is needed. In this case, simply remove the filter sock plate and install the perforated foam block plate and then place the included foam sponge block filter in place.


Adjustable Water Level
Water level in the sump is adjustable from 7” to 9.5” to accommodate for the water height requirements for different protein skimmers.


Self-Adjusting Foam Block (PAT PENDING)
As the water level is adjusted by sliding the wall up and down, the foam block sponge filter and the perforated plate that it sits on will also move up and down automatically. This is important to maintain the correct location of the foam block sponge filter with respect to the sump water height.


Probe Holder
All Emerald sumps come with a probe holder that can hold up to three probes. The two outside holes are 0.63” in diameter and the center hole is 0.8” in diameter to fit different sized probes.


Hose Holder
All Emerald sumps also come with 4 holes in the top support brace for holding in place 1/4” OD tubing from reactors, dosing pumps, ATO, etc.

  • Quality built By Robert on 8/8/2017

    I have the emerald 26 under my Sc Aqaurium 80 gallon with rReef Octopus 150SSS Elite. Sump built good but I don't get enough flow from skimmer into refugium like I want so stuff builds up in both compartments. The way the skimmer is built and it's size does not all for good flow from skimmer into refugium section
  • very pleased By Scott on 4/11/2017

    Sump is well built and looks good. It did arrive with 1 of the sliding gate screws broken. No big deal. I am using this on a 100 gal freshwater tank so the setup is different then most. The VarioS-6 (1720 GPH) sits very nicely in the return section. I have the water level set at max giving me lots of contact surface for various filter pads placed in the center section. Bio balls are in place in the filter sock outflow as well as the overflow section to the return. A few months of use will really show how well this works. I'm running the tank very near the max flow it's 1" overflow will handle. This results in more sump noise then expected (still quieter the the old system). More work on the plumbing to see if that helps or if it's the sump.
  • Good Quality By Mantas on 9/26/2016

    I bought this sump for my Fluval M90 system to increase water volume. I added with this sump another 10 gallons of water and it works perfect. I also got BRS recommended skimer
    "Octopus 150sss"that fits in this sump. It is running now for couple of weeks and so far i love it. And again BRS was extremely fast with shipping.
  • Well built sump/refugium By Steve on 5/11/2016

    Looks great and is very quiet. The 4" filter sock has to be compressed into an oval shape to fit the opening. It would be nice if they made the chamber a little bigger to get the sock in and out.
  • Amazing Quality! By Chris on 2/9/2016

    I was super stoked to get this product in, after 2 weeks of being setup; I have to say that this is an AWESOME product! Great quality and well thought out design!! The only thing I wish was that the skimmer compartment was a tad bit larger. Overall AMAZING product!!!!

Product Questions

With the skimmer section foot print being 8.25" X 10", what is a good skimmer to fit in this section. I have been having problems trying to find the best skimmer to fit in these specs. Is there a skimmer that you would recommend for the emerald 26 for a 90 gallon with a medium bio load?
Question by: todd wilson on Apr 11, 2016 10:08:00 AM
Great question!
I have included 2 skimmers below which will both work well, the 150SSS and the 110 SSS. We would recommend the 150 if your tank will be going in the future. Feel free to let us know if you have any further questions!

What is the sock size? Could you recommend socks that will work with this sump?
Question by: Alex on Jul 27, 2016 11:55:00 AM
Hi there,
The trigger sumps use 4” filter socks, and we would suggest using either the BRS 4x8” or 4x14” Felt filter socks. The included socks are right around 12” long so our 14” models may be a little long, but that will not affect performance. If a long sock is a concern then we would suggest sticking with the 4x8” felt socks.
Thanks for the question and if you have any more just let us know. Thanks!

Hi bulkreefsupply,
I'm really interested on your emerald sump26
I got 100gallon tank and I'm worried if it's enough to get the emerald sump26?
And I'm also worried about the drain input fittings Coz my overflow has a 2 input fittings Coz were using the ghost overflow box is there anyway to make it 2 input fittings?
Question by: Jacob on Feb 2, 2016 11:14:00 PM
Great question!
You certainly can get by with the emerald 26 as long as you have enough room for filtration and reactors and skimmers! For the issue with the overflow box having 3 drain lines you can simply take 1 drain line as the emergency and run it to another part of the sump. This would only flow if the other drain lines were blocked. Feel free to let us know if you have any further questions!

Can you recommend a couple skimmers below $500 that will fit in the 26 sump?
Question by: Dan on Apr 8, 2016 7:19:00 AM
Hey there!
I have included a few skimmers below which can work well in a emerald 26! Feel free to let us know if you have any further questions!

Answer by: Connor (Admin) on Apr 12, 2016 5:20:00 PM
Will this be suffice for a 200 gallon saltwater tank. if not what model would be.
Question by: Eric Roeder on Feb 18, 2016 7:50:00 AM
Great question!
This will work well as long as you have enough room in the skimmer compartment for the skimmer of you choice. Feel free to let us know if you have any further questions!
