The AvidAqua NeaterHeater is a magnetic mounting system designed to securely hold up to two aquarium heaters in place without the need for traditional suction cups. This innovative solution eliminates common failure points associated with standard heater mounts while ensuring heaters remain properly positioned for safe and consistent temperature control within saltwater or freshwater systems. Utilizing a sealed ModMag magnet system, the device features ultrasonically sealed magnets that prevent water intrusion and corrosion for long-lasting reliability. It includes Slide-Loc tool free silicone retention to keep heaters firmly against glass or acrylic aquarium walls up to three eighths of an inch thick. The low profile design accommodates most common glass or titanium heater sizes and maintains proper spacing between dual units. This mounting system is ideal for reef aquarists seeking a redundant heating setup who want to avoid the maintenance hassle of replacing failed suction cups. It provides peace of mind by preventing heaters from slipping, sagging, or contacting other equipment during operation or water changes. Backed by an AvidAqua lifetime warranty, it offers a durable upgrade for any sump or display tank requiring reliable heater placement.
