Sapphire 39 Sump – Trigger Systems

Proudly made in the USA (Dallas, TX), Trigger Systems has earned a reputation for precision-engineered sumps that deliver custom-quality features in a production-ready package. The Sapphire39 is part of Trigger’s signature Sapphire Series, offering reef-ready functionality, refined aesthetics, and thoughtful design enhancements that elevate any advanced reef system.

Built with durability and longevity in mind, every Trigger sump includes a full top support brace made from a solid material to resist bowing over time. Rounded corners provide enhanced strength, and the Sapphire blue coloration helps suppress unwanted algae growth by blocking light from sensitive sections.
