AvidAqua MTO – Magnetic Tubing Organizer

The Next Generation of Magnetic Tube Holders

For years, reef keepers have struggled with poorly designed tube organizers that use glued acrylic holders prone to rust and failure. The MTO Magnetic Tubing Organizer changes the game with a durable, leak-proof, and modular solution for managing your dosing, testing, and return lines.

Rust-Free & Secure with ModMag Technology

Unlike traditional tubing holders that glue magnets inside, risking saltwater intrusion and rust contamination, the MTO features the ModMag—a double-sealed, ultrasonically welded ABS enclosure that prevents leaks and corrosion. The built-in “Shake-Test” feature lets you confirm that the magnet remains completely dry and safe, ensuring your reef stays protected.

No More Thumbscrews—Just Slide & Secure

Tubes are firmly held in place with the Slide-Loc® silicone gasket system, eliminating the need for fragile thumbscrews that can strip, break, or pinch tubing. Simply slide your tubing in, and it stays secure—no adjustments needed.

Designed for Dosing & Automated Testing Systems

The MTO organizes up to 7 tubes—including 5 x 1/4” lines and 2 x 3/8” lines. It also features two guide tubes to keep automated testing system pickup lines, like those from the Neptune Systems Trident, positioned correctly to prevent air intake and debris pickup.
