Aqueon offers an assortment of heaters that provide the warmth essential to tropical fish’s survival and overall wellbeing. Heaters are built with different wattages, so it is imperative choose a heater that best fits the aquarium size. Review a heater wattage and aquarium size comparison chart to ensure the appropriate heater is installed inside the aquarium. It is also suggested to do research on the type of fish inside the aquarium so that the water temperature is maintained at a level that the fish breed thrives.
Heaters can be adjustable or preset to heat up to a certain temperature or for specific aquarium sizes. Preset heaters require no adjustment and have been calibrated to 78°F. Adjustable heaters have manual temperature knob that ranges from 68° to 88°F. It is important to understand whether or not the aquarium heater is programmed to turn off when not fully immersed in water, which is helpful during water changes when the water level goes very low. Some heaters can malfunction if not designed to withstand being out of water. Carefully chose the heater that works best for the situation.
