Trigger Systems Ruby CUBE Sump - 20 inch Trigger Systems specializes in aquarium sump manufacturing. They manufacture all sumps here in the USA (Dallas, TX). Trigger Systems build each sump as if it were their own. 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. They also round instead of squaring the corners which exponentially increases the strength of the corner.Trigger Systems have taken feedback from their customers through the years to enhance their products. Small 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. All Trigger Systems 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 RUBY series sumps are loaded with features and come with the trademark dark RUBY translucent red material. RUBY sumps have the same designs as the CRYSTAL but have the following differences: Same or slightly larger dimensions RUBY red coloring to block light and prevent unwanted algae growth in other sections Probe holderSome additional features of the RUBY sumps are: Locking Filter Sock Holder Adjustable Water Height (ELITE and CUBE models) Protein Skimmer section Refugium section Adjustable Water LevelWater level in the sump is adjustable on the following RUBY sumps: Ruby 20C Cube from 7” to 9.5”, Ruby 30E and Ruby 36E Elite from 7” to 10”. This feature is to accommodate for the water height requirements for different protein skimmers.Locking Filter Sock HolderFilter 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.
