Review: Buen calentador de dimensiones adecuadas y buenos materiales para tanque NANO MARINO los controles de temperatura están bien diseñados, se agradecería que contara con protector inferior para el tubo de vidrio PYREX puesto que no lo lleva, el LED es muy brillante y detecta la variación de temperatura, lo debes dejar aclimatar en el tanque más de media hora para obtener buenos resultados, recomiendo su compra.
Review: Fonctionne très bien!

## Questions & Answers

**Q: How far from the top of the water can this be?**
A: It should be fully submerged at all times, and can be anywhere in the tank.  You can place it vertically or horizontally, but do not bury it or allow anything to press up against it.

**Q: How do I know that the heater is on**
A: Theres a red led that's turns on when its heating.  It's only on when the heater is heating, if the water temp is at the heater set point then it turns off

**Q: Where is the minimum water line, exactly? i want to mount it to my tidal 55 hob filter, but i'm afraid it's sticking too much out of the water.**
A: On all submersible aquarium heaters you can look at the glass tube and there will be a recommended water line to maintain the heater in the water. Its usually about 1/4 to 1/2 inch below the thermostat controls. If the heater is on and the glass isn’t submerged it can crack or break very easily.

**Q: What is the length of the 200 watt heater?**
A: Approximately 12"- 13", depending on whether you want to include the knob as part of the length.
