Trigger Systems Crystal Sumps

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. The CRYSTAL series sumps are reasonably priced and have the same design and quality as Trigger Systems' RUBY series sumps but with all clear material. The CRYS18C can be used as a berlin style sump or a refugium style sump. Some features of the CRYS18C sump are: Locking filter sock holder Solid top support brace to prevent bowing Foam filter block Protein skimmer section Refugium section Section Details & Water Flow Path The CRYS18C has 3 main sections. 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
