It is factory set to 78 degrees F, holds within about 1.8 degrees, and shuts itself off when the water reaches temperature, so there is no dial to fiddle with and no risk of cooking a small tank. The heat-resistant quartz tube mounts with the included suction cups and hides behind rock or plants. Pair it with a thermometer such as the \u003ca href=\"https:\/\/squeakysaquatics.com\/products\/aquatop-atsd01-stick-on-digital-thermometer\"\u003eATSD-01 stick-on strip\u003c\/a\u003e and browse the

shrimp. Choose an adjustable heater if you need a cooler or warmer set point.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs 10 watts enough?\u003c\/strong\u003e For a tank up to 3 gallons in a normally heated room, yes. If the room drops into the low 60s, step up to the 25 W Pisces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it run out of water?\u003c\/strong\u003e Never let the water level drop below the heater while it is plugged in; unplug it for water changes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need a controller?\u003c\/strong\u003e Not for a nano tank; the built-in thermostat cycles it.
