Itc M-Rack

The M-Rack Dosing Tube Holders deliver professional-grade organization for your reef system's dosing setup. Crafted from premium Perspex® cell cast acrylic—not 3D printed—these UK-manufactured holders maintain their deep black finish under blue lighting while resisting chemical degradation. Each compact holder (40mm x 45mm) securely manages up to five 5mm OD dosing tubes, keeping your tubing neat and tangle-free. The modular magnetic mounting system requires one M-Rack PUK magnet per holder (or two for loop-style installation), offering flexible placement inside the tank, sump, or externally. Sold as a pair, these holders integrate seamlessly with the expandable M-Rack ecosystem, allowing you to scale your dosing infrastructure as your aquarium evolves. Magnets sold separately.
