NeaterHeater Pro - Dual Aquarium Heater Mounting System

Reliable, Suction-Cup-Free Heater Mounting Solution

• Holds Two Glass or Titanium Heaters
• Ultrasonically-Sealed, No-Rust Magnets
• Suitable for Glass or Acrylic up to 1/2" Thick
• AvidAqua Lifetime Warranty

The AvidAqua NeaterHeater is a magnetic, suction-cup-free mounting system designed to securely hold up to two aquarium heaters in place. It eliminates the common failure points of traditional heater mounts while keeping heaters properly positioned for safe, consistent temperature control.

Using AvidAqua’s sealed ModMag magnet system and Slide-Loc tool-free silicone retention design, the NeaterHeater provides a reliable, low-profile solution for mounting glass or titanium heaters on glass or acrylic aquariums up to 1/2" thick.

Secure Dual-Heater Mounting

The NeaterHeater is designed to hold up to two glass or titanium heaters, making it ideal for systems with a redundant heating setup. Heaters stay firmly positioned on the aquarium or sump wall, preventing slipping, sagging, or contact with other equipment during normal operation or maintenance.

Compatible with most common heater sizes, the NeaterHeater installs cleanly on glass or acrylic up to 1/2" thick and keeps heaters properly spaced.

With the NeaterHeater Pro you get two ModMag sets that can be joined together with the included adapters to make one stronger bar, or if you have extra-long heaters, they can be placed independently at each end of the heating elements.

Sealed ModMag Magnetic System

AvidAqua’s ModMag mounting system replaces suction cups with fully sealed, ultrasonically sealed magnets. Each magnet enclosure is pressure tested to prevent water intrusion and corrosion, eliminating one of the most common failure points of magnetic aquarium accessories.

A built-in shake test allows you to quickly verify that the magnet seal remains intact, providing long-term confidence in the safety of your system.

Slide-Loc Retention and Modular Design

Heaters are secured using patent-pending Slide-Loc technology, which holds heaters in place without annoying thumbscrews. Installation is tool free, and adjustments are quick and simple.

Included ModMag expansion adapters allow additional magnets to be added for increased holding power when needed. The ModMag platform also supports other compatible accessories, allowing multiple tools to share a single, clean mounting solution. Backed by an AvidAqua Lifetime Warranty, the NeaterHeater is built for long-term reliability.
