So, they finally perfected the “titanium” submersible aquarium heater. You never have to worry about smacking it against the side of a tank or container. Ehhhhhhhhhhh sort of.
I watched someone do a water change and drain the tank and left their titanium sizzling and then it shut off.
Yeah, there is a thermal overload breaker that kicks off the heater before it bursts. But don’t rely on it!
I like THESE titanium heaters and use them in all my tanks. The Popetpop 400W titanium.
