Aqueon Preset Fish Tank Heater 100 watts Black 3.5" x 1.5" x 7.75"

Keep your tropical aquarium at the perfect temperature with the Aqueon Preset Fish Tank Heater at 100 watts. Pre-calibrated to 78°F — the ideal temperature for most tropical freshwater fish — this fully submersible heater requires zero adjustment. Just submerge it and let it work. Built from shatter-resistant quartz glass, it's designed to handle the demands of an active aquarium, while the automatic safety shut-off prevents overheating and protects your fish and equipment.

A built-in LED indicator light glows red whenever the heater is actively warming the water, giving you instant visual confirmation it's working. At 100 watts, this heater is well-suited for larger freshwater aquariums that need reliable, consistent heat.
