IceCap 2-Port Magnetic Tubing Holder — Dosing Mount (IC-MTH-2)
The IceCap 2-Port Magnetic Tubing Holder (SKU: IC-MTH-2) is an authentic, studio-grade sump organization accessory distributed by CoralVue to bring absolute structural security and a professional presentation to your automated liquid dosing lines. Automated dosing systems—delivering elements like calcium, alkalinity, magnesium, or carbon sources—are essential for maintaining a stable marine reef or freshwater ecosystem. However, leaving loose tubing lines dangling over your sump is a significant hazard. Shifting cords or high-velocity water currents can easily displace loose lines, causing them to drip outside your sump, tangle into equipment impellers, or siphon tank water backward. The IC-MTH-2 holds your lines firmly over the water column to eliminate these risks.
Constructed from heavy-wall, crystal-clear cell-cast acrylic, this 2-port bracket is built to withstand continuous exposure inside humid, high-salinity marine stands. Traditional tubing clips rely on cheap rubber suction cups that harden, collection organic slime, and slide out of position within months. The IceCap series bypasses this flaw completely by using a specialized Dual-Sealed Magnetic Mount. Both the internal wet-side bracket and the dry-side external backing block feature powerful magnets completely encased in acrylic sheets to prevent rust. Non-conductive nylon thumbscrews line both channels, allowing you to secure your lines without compressing or restricting the fluid path.
Key Features
Prevents Back-Siphoning Hazards: Holds your automated dosing lines securely above the sump waterline, breaking any potential back-siphon suction path.
Universal Fluid Line Adaptation: Form-milled ports easily accept standard 1/4-inch outer diameter (1/4in) flexible silicone, vinyl, or rigid polyethylene RO/DI lines.
Zero-Tool Adjustable Mounting: Simply slide the magnetic assembly along your glass or acrylic baffle to easily reposition your dosing drop zone during cleaning.
(Note: This retail package includes (1) 2-port wet-side acrylic tubing holder with pre-installed nylon thumbscrews and (1) dry-side magnetic backing pad. Dosing pumps, tubing lines, and liquid supplements are sold under separate product categories).
