Fluval E100 Advanced Electronic Heater 100 W, up to 30 US Gal / 120 L

An electronic, digitally-controlled heater for tanks up to 30 US gallons, using Fluval's VueTech monitoring system to give a precise temperature readout rather than relying on a mechanical dial's rough estimate. Well suited to planted tanks and sensitive livestock where consistent, accurately-held temperature matters more than it does in a hardier community setup.
