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


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.


Trigger Systems specializes in aquarium sump manufacturing. They 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.
Trigger Systems has taken feedback from their customers through the years to enhance their line of awesome sumps. Little things in the design aspect will pay off considerably when putting the sumps to use. A simple example is that they 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.

Product Questions

What skimmer would you recommend for good fitment. I have this sump on my 90gal reef
Question by: Christopher Chaplin on Jul 7, 2016, 5:37 AM
Depending on your budget we would suggest looking into the Skimz Kone SK184 or the Skimz Kone SK181. Both will fit well and leave you with a little extra room around the skimmer if you need to put a pump in for a reactor or anything. We really like the SK184 because of the performance the Sicce Needlewheel pump provides.

I'm looking at maybe buying the Crystal sump 30, for my 90 gallon tank, what size overflow box and return pump would you recommend?
Question by: Mark on Apr 9, 2016, 4:31 PM
Great question!
We would recommend the Synergy reef overflow box, or one of the large or extra large CPR overflow boxes. For a return pump you will want one with a minimum of 900 GPH flow. Feel free to let us know if you have any further questions!
