The Reef S3/F ‘Frag’ Series is a shallow, rimless version of the S3 Classic, featuring state-of-the-art polycarbonate jump lids. Designed for coral frag propagation and small reef setups, it delivers premium build quality, sump filtration, and advanced features in a compact design.

The Frag S3 is a premium frag system designed for clarity, accessibility, and efficient coral growth.

Built with Opti-Clear glass, the tank features a clean rimless design, laser-etched logo, and a white laminate base for a modern finish. A polycarbonate jump lid and twin weir intake system (surface and low) provide consistent, efficient water flow, while the integrated ATO RO reservoir adds convenience and stability.

The 900mm tall cabinet is constructed from 100% corrosion-resistant, powder-coated aluminum, making it ideal for marine environments. It includes a dedicated power management centre, storage and dosing shelf, adjustable levelling feet, and full cable management with multiple access doors and seamless routing to the sump.

Water management is streamlined with pre-installed, quick-fit plumbing, including a fine-tune gate valve, non-siphon check valve, reactor feed taps, and adjustable outflow nozzles. The tinted glass sump is roller-mat ready (no filter socks) and features a Triton-style algae tray, algae trap, and media baskets for flexible filtration.

Available in black or white, the Frag S3 is purpose-built for hobbyists looking for a clean, functional, and high-performance frag system.

Price is for Tank and Cabinet. Delivery and install are seperate optional purchases.
