Trigger Systems Emerald 26 Sump

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

Trigger Emerald 34 Sump


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 throught the "Trigger Symbol" cutout into Section 3.  Section 3 is the refugium section. the water then flows over teh 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 (bags 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 (Patent Pending)

Each Emerald sump comes with two plates that can be placed into Section 1: Filter Sock Plate or Foam Block Plate

The filter sock plates 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 the filter socks are not desired or in the case when the filter socks need to be changed or cleaned but replacement 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 plance 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 (Patent 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.

Amazing sump!! Great build quality bedy happy. The only issue was the probe holder does not have screws to secure your probes in tight. I don't want to put the doors on my stand and want to show it off. Used green PVC pipe and fittings from here too to make it look even better. Also used black spa flex. I didn't not used the drain fittings that came with it. One of the acrylic brackets came off but I solvent it back on.
