Trigger Systems specializes in aquarium sump manufacturing and are based here in the USA (Dallas, TX). All Trigger sumps come with a full top support brace which is made of a solid piece of material to prevent bowing over time from the humidity and water pressure. They also round the corners instead of squaring them which exponentially increases the strength of the corners.

Each Emerald sump comes with two plates that can be placed into Section 1:
The filter sock plate is installed when the included 100 micron filter socks are desired.
- Filter Sock Plate
- Foam Block Plate
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 - 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.
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.
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.
