The AvidAqua ModMag Giga is a heavy-duty, modular magnetic mount for big jobs on thick-pane aquariums. Use it to secure accessories inside or outside the tank—powerheads, return lines, tubing, cord guides, sensors, and more—without drilling or permanent hardware.
Giga-strength magnet pair grips confidently through thick glass/acrylic (verify your pane rating)
Modular face plate with multiple slots/holes for zip ties, clamps, and custom brackets
Reef-safe construction—encapsulated, corrosion-resistant magnets and marine-grade hardware
Low-profile design keeps a clean look and minimizes flow shadows
Inside/Outside versatility for organizing gear, cord management, or mounting equipment
Secure wavemakers/gyre cords and keep them routed cleanly
Mount tubing (dosing/ATO/CO₂), probes/sensors, or airline manifolds
Anchor return lines or small spray bars
Temporary hold for frag shelves or light accessories during maintenance
Clean the pane (remove salt creep and film).
Place the wet side inside the tank and align the dry side outside.
Use the slots/holes to zip-tie or clamp your accessory.
For very heavy loads, support from below or split weight across two ModMag units.
Periodically remove and wipe down both halves to prevent buildup.
Note: Always verify the ModMag Giga’s pane-thickness rating against your aquarium before use. Keep sand/grit away from mating surfaces.
