Why You’ll Love It Keep your aquarium at the perfect temperature with the hygger 113 LCD Quartz Heater, engineered for fast heating, stable temperature control, and long-term durability. Designed for medium to extra-large freshwater or saltwater aquariums 40 to 264 gallons, this heater combines an explosion-proof quartz tube, an intelligent LCD controller, multiple safety alarms, and uniform heat dissipation to protect your fish, plants, and coral. Key Features Fast, Stable, & Uniform Heating Nickel-chromium heating wire ensures a rapid warm-up and consistent temperature throughout the tank. Quartz sand filling inside the rod provides uniform heat dissipation, preventing hotspots. Designed to maintain a stable environment for sensitive species like discus, shrimp, and reef inhabitants. Smart External LCD Controller The HG113 LCD quartz heater has a separation design of the heater and the controller. The external LCD high-definition controller displays the current water temperature, set temperature, and heating status. Large dual-display screen shows Set Temperature & Current Water Temperature at the same time. Wide adjustment range: 59°F to 93°F (15–34°C) with an accuracy of ±0.1 °F. Precise 1°F increments using the SET button. Work indicator light: Flashing = heating, Solid = temperature reached External circuit prevents water exposure, reducing risk of electrical damage. Features sound alarm flashing warning lights for immediate alerts. Multi-Level Safety Protections The LCD quartz heater includes all four intelligent protection codes shown in the screenshots: LL→ Water temperature below 59°F (too cold). HH→ Water temperature reaches 94°F (overheating). EE→ Probe failure; heater must be replaced. L1→ Heater not fully submerged. Additional built-in safety: Dry burn protection: heater automatically shuts off if exposed to air or the tank’s water level is low. Overheating protection: instantly stops heating to prevent damage when exceeding 94°F (34°C), cease heating to prevent overheating and potentially harming automatically. Low temperature protection: alerts you before the water temperature falls below 59°F (15°C). The controller will sound an audible alarm. Through the intelligent chip, the heater stops heating when the water temperature exceeds 93 ℉, and automatically turns on the heating when it is lower than 59 ℉, helps safeguard your aquatic life and prevent expensive tank crashes. Explosion-Proof Quartz Heating Tube Made with high-strength quartz sand glass, resistant to sudden temperature changes. Anti-corrosion, suitable for both freshwater and marine tanks from 40 to 260 gallons. Heat-resistant ABS protective outer shell keeps fish from contacting the hot surface. Directional heat slots improve water circulation and heating efficiency. It is suitable for home fish tanks, fish markets, public aquariums, fish farms, ponds, and other captive aquatic life settings. The extended cable lengths provide flexibility for large aquarium setups, sumps, and stands. Stable, Fast, and Heat Dissipation The HG113 quartz heater is heated by stable nickel-chromium electric heating wire, thickened quartz glass explosion-proof tube for heat conduction, and ABS plastic shell for protection, making it stably generate heat in fish tanks. Memory Function The hygger LCD quartz heater has a memory function that stores your set temperature. Once power is restored, it will automatically resume operation according to the saved settings. Usage Tips How to choose the right fish tank heater Wattage= Fish tank (length × height × width) ÷ 1000 × 2 Caution: When changing the water in your aquarium, please unplug the heater first and allow the heating rod to cool down for a while before removing it. Tips: By pressing and holding the setting button on the controller for 2–3 seconds, you can switch between ℉ and ℃.
