Full Details

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.

  • Skimmer compartment By david on 9/16/2017

    It's a well constructed sump the skimmer measurements are not 12x13.5 with the sock area measures 11x8.5 I have a skimmer 7.5x7.5 barely fits the socks sit behind it which isn't very easy to get to
  • Great Sump By Thekekg on 2/17/2017

    Great Sump feels sturdy and solid. no complaints. Price is a bit high considering it really doesn't do anything special other than hold water but all sumps are expensive unless you feel like doing a DIY.
  • Perfect. By Michael on 2/13/2017

    Perfect in every way. Good size refugium, large skimmer area. Plenty of space for extra pumps, heaters. Etc.

Product Questions

How thick is the acrylic and will it bow out over time?
Question by: Dave VonderHaar on Mar 27, 2016 10:17:00 AM
Great question!
This acrylic will be around 3/8" thick depending on location and from our experience doe not have much bowing in the several months we have had them running. Feel free to let us know if you have any further questions!
