xOverview
The HTSPPXT Aquarium Heater is a compact, submersible heater designed for 20–40 gallon tanks. With adjustable power options (100W, 200W, 300W, 500W) and a smart LED controller, it helps you set and monitor your tank's warmth with ease. Its slim 7x1.69x1.29 inch profile lets it blend into your aquatic landscape while delivering dependable performance that supports stable conditions for diverse aquatic life.
Smart heating for everyday tanks
Inside, the heater uses high‑quality nichrome wire and silicon carbide for rapid warming, while a quartz sand middle layer spreads heat evenly to reduce hotspots. The outer glass tubing and ABS shell shield the unit from daily wear, helping it stay discreet behind decor while protecting the tank inhabitants from sudden temperature shifts.
Dual control and safety at a glance
The LED controller displays temperature in ℉ or ℃ and lets you fine‑tune with simple plus and minus controls. Safety features include automatic shut‑off when the water temperature rises above 94℉ and a dry‑run safeguard if the heater bar is exposed, both accompanied by clear alerts to help you monitor conditions at a glance.
Ease of use and reliable operation
Two sturdy suction cups provide secure mounting on the tank wall or bottom. If power is interrupted, the controller’s memory function returns to your last setting when power is restored. Remember to fully submerge the heater before use to ensure proper operation and protection of your tank environment.
Care, maintenance, and longevity
For longevity, clean the heater rod regularly, unplug and allow it to cool 15–20 minutes before removing the housing, and be mindful that the heater’s relay is a wearable part that may require replacement after 1–2 years depending on conditions. If you have questions, our team is ready to help you optimize performance.
