AvidAqua NeaterHeater - Dual Aquarium Heater Mounting System

AvidAqua NeaterHeater – Magnetic Dual Heater Mount

Say goodbye to slipping suction cups and unreliable heater clips. The NeaterHeater delivers a clean, secure, and maintenance-free way to mount your aquarium heaters, keeping them exactly where they should be for consistent and safe temperature control—available now at Reef Supplies Canada.

Built for reliability and ease of use, this magnetic mounting system uses sealed components and a smart retention design to eliminate common failure points while simplifying installation and adjustments.

Reliable, Suction-Cup-Free Mounting

The NeaterHeater replaces traditional suction cups with a robust magnetic system, ensuring your heaters stay firmly in place without sagging or detaching over time. It maintains proper positioning on your tank or sump wall, even during maintenance or equipment adjustments.

Secure Dual-Heater Support

Designed to hold up to two glass or titanium heaters, the NeaterHeater is ideal for systems using redundant heating. It keeps heaters properly spaced and stable, preventing contact with other equipment and reducing the risk of damage or inconsistent heating.

Compatible with most standard heater sizes, it mounts cleanly on glass or acrylic aquariums up to 3/8" thick.

Sealed ModMag Magnetic System

At the core of the NeaterHeater is AvidAqua’s ultrasonically sealed ModMag magnet system. Each magnet is pressure tested to prevent water intrusion and corrosion, eliminating a major point of failure found in many magnetic aquarium accessories.

A built-in shake test provides a quick and easy way to confirm the integrity of the magnet seal for long-term peace of mind.

Slide-Loc Retention Design

The patent-pending Slide-Loc system securely holds heaters in place without the need for thumbscrews or tools. Installation is quick, adjustments are simple, and the low-profile design keeps your setup clean and uncluttered.

ModMag expansion adapters are included, allowing you to increase holding strength if needed. The modular platform is also compatible with other ModMag accessories, giving you flexibility to expand your setup over time.

NeaterHeater vs. NeaterHeater Pro

Both models feature the same Slide-Loc retention system and sealed ModMag magnets, but differ in strength and versatility:

NeaterHeater includes one ModMag Mega and supports glass or acrylic up to 3/8" thick.
NeaterHeater Pro includes two ModMag Mega magnet sets, supports thicker walls up to 1/2", and can be configured as a single stronger mount or split for longer heaters.
