Stronger, Safer & Smarter Than Traditional Magnets

Unlike traditional acrylic-encased magnets that rely on glue and risk leaking over time, the ModMag Giga is ultrasonically welded and double-sealed, preventing water intrusion and ensuring long-term safety for your reef. The built-in shake test feature provides instant confirmation that the seal remains intact—giving you peace of mind with every use.

Customizable & Expandable with an Open-Source Design

The ModMag system is open-source, meaning it’s compatible with an expanding lineup of AvidAqua accessories as well as third-party and DIY creations. From frag racks and tubing organizers to camera mounts and feeding stations, this modular magnet is designed to evolve with your reefing needs.
