Trigger Systems specializes in aquarium sump manufacturing. We manufacture all sumps here in Dallas, TX. We build each sump as if it were our own. We take pride in the robustness, efficiency of the design and visual appeal of our sumps. All sumps come with a full top support brace which are made of a solid piece of material. Without this the sump will over time begin to bow out from the humidity and water pressure. We also round instead of squaring the corners which exponentially increases the strength of the corner.
We have taken feedback from our customers through the years to enhance our products. Small things in the design aspect will pay off considerably when putting the sumps to use. A simple example is that we always maximize the distance between the protein skimmer location and the return pump in an effort to minimize the chance for micro bubbles returning to the display. All of our sumps come with a refugium section that can be used to house other equipment if a refugium is not desired on the particular setup.

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
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
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.
