Trigger SystemsSKU: SAPPHIRE20C



The Sapphire series is identical to the Emerald series except that it comes in a limited edition Sapphire blue color. Several features of this series are not found anywhere else. Some of the features of the SAPPHIRE20C are:

  • Interchangeable plates (Patent Pending)

  • Laser etched lid to prevent splashing and reduce noise

  • Adjustable water level

  • Self adjusting foam block platform (Patent Pending)

  • Dual platforms

  • Laser engraved water level indicator

  • Three position probe holder

  • 0.25″ hose holder for dosing and ATO inputs

  • Protein skimmer section

  • Refugium section

  • Sapphire blue coloring to block light and prevent unwanted algae growth in other sections


The SAPPHIRE20C has 4 main sections. Water enters the sump into a dedicated section where the water will then flow over into Section 1. Section 1 is the configurable interchangeable plate area allowing for filter sock and/or foam block mechanical filtration. This area is covered with a lid to prevent water splashing and reduce noise. 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 adjustable water level baffle through a platform that contains a foam filter block and then under the last baffle into Section 3.

Section 4 is the return section where the return pump will sit, pumping water back to the display tank.

The SAPPHIRE20C comes with the following accessories for Section 1:

  • Filter Sock Plate
  • 4″ Filter Socks (100 micron rating)
  • Foam Block Distribution Plate
  • Filter Foam Block

The Filter Sock Plate can be installed with filter socks as shown. The SAPPHIRE20C has a single 4″ sock. SAPPHIRE34 model shown in the images.

The Foam Block Distribution Plate is perforated with holes and can be used when 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 and you want to maintain some level of mechanical filtration. In this case, simply remove the filter socks and install the Foam Block Distribution Plate with the foam block.

The Foam Block Distribution Plate may also be used on top of the Filter Sock Plate with filter socks. This configuration helps to distribute the water more evenly across all socks so that the filter socks will last longer before clogging and will clog at the same time. This also helps to silence the water noise by slowing down and spreading the water more evenly across the surface area of all of the socks. In this configuration, the foam block filter can be placed on top to enhance even further the silencing and distribution of water and also allow even longer times before the socks become clogged by providing a pre-filter before the socks. This configuration is shown in the image and is the default configuration.



The SAPPHIRE20C comes 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.


Subtle water level height indicator is laser engraved on the inside wall to help when setting the adjustable water level to to the desired water height based on protein skimmer requirements.


All Sapphire sumps also come with 4 holes in the top support brace for holding in place 1/4” OD tubing from reactors, dosing containers or ATOs.


The laser etched lid over the interchangeable plate section allows for easy access to the filter socks and foam filter while providing suppressed noise and splashing.
