Trigger Systems Crystal Sump – 30 inch Temporarily Out of Stock


SKU: 6E81634 Category:


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.

  • Dual platforms
  • Protein Skimmer section
  • Refugium section

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.

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.

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.
