SAPPHIRE20C SECTION DETAILS|
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.

Interchangeable Plates
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.


Three Slot Probe Holder
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.

Laser Engraved Water Level Indicator
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.

Dosing, ATO 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 containers or ATOs.

Laser Etched Lid
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.
