Trigger Systems Crystal Sump 18x18 cube

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 CRYSTAL series sumps have the same design and quality as the RUBY series sumps but are made of all clear material. The differences when compared to the equivalent RUBY sump:
Same or slightly smaller dimensions
All clear material instead of the RUBY red
No probe holder
Some of the features of the CRYSTAL sumps are:
Locking Filter Sock Holder
Dual platforms (SUMP model)
Protein Skimmer section
Refugium section

Dual Platforms
CRYSTAL SUMP models come with dual platforms in the space before the return section. The top 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.). This feature is on the SUMP models only.

Locking Filter Sock Holder
Filter socks snap and lock into the filter sock holders to secure the filter sock from falling out when it becomes clogged and needs to be cleaned or replaced. The 4” filter socks are 100 micron rating.

Draw String Tabs
Tabs are located on the top support brace in front of the 1” bulkhead fittings which are included. The purpose of these tabs is to provide a location for tying off 7” diameter filter socks that have draw strings.

Section 1 of the CUBE design is where the water from the main tank enters through the filter sock. This is the section where the protein skimmer typically sits. Water flows from this section through a slit in the baffle into Section 2. Section 2 is typically used as the refugium section. Having the refugium facing the front is a nice feature allowing easy maintence and visibility of the refugium. Water flows to the right and then towards the back over the baffle through the overflow teeth. The water then goes through a foam block which is provided and under a baffle into Section 3. Section 3 is the return section where the return pump will sit.
