Protect your aquarium from one of the most common causes of livestock loss with the Inkbird ITC-306A WiFi Dual Digital Aquarium Heater Controller. Designed specifically for aquariums, this smart controller adds an extra layer of protection between your heaters and your aquarium by maintaining a stable water temperature and automatically cutting power if temperatures exceed your programmed limits.

Unlike standard heater controllers, the ITC-306A features two waterproof aquarium-safe temperature probes and dual heater outlets, allowing you to safely operate two heaters simultaneously while providing redundant temperature monitoring for greater peace of mind.

Monitor and adjust your aquarium from anywhere using the free Inkbird mobile app over your 2.4GHz WiFi network. Receive instant alerts if temperatures become too high, too low, the probes disagree, or the controller detects a sensor issue—helping protect your aquarium even when you're away from home.

Whether you're running a reef aquarium, freshwater tank, shrimp aquarium, or large predator system, the ITC-306A delivers reliable, accurate temperature control to help keep your aquatic life safe.
