aquarium & fish tank heaters, chillers & thermometers
Whether you need to keep your tank cool or raise the temperature so it is toasty warm, Petco has the aquarium heater and chillers to keep your water temp just right.
Aquarium heaters are essential equipment for most freshwater or saltwater setups. A fish tank heater is especially necessary if you have popular tropical species like angelfish, blue danios or neon tetras that like basking in warm water, because these species, and many others like them, generally require a water temperature above 74° to thrive. Aquarium heaters also help keep the temp stable, so your community doesn’t have to deal with undue stress or serious health problems. However, even if your fish tank heater indicates degrees, an aquarium thermometer should be used to ensure the reading is accurate. If you have a large tank, you may need two smaller fish tank heaters at opposite ends of your setup. Doing this helps maintain a stable temperature throughout your habitat, so no matter which side your tang or triggers take to, they’ll be comfortable.
Some aquatic pets like to hang out in cooler climates. For species like goldfish, loaches and some barbs, a chiller helps keep their water conditions at an optimal temperature. Especially since some equipment like UV sterilizers, water pumps and lights can heat the tank higher than desired. During the summer months, you may also need an aquarium chiller to keep conditions comfortable for your gilled guys and gals. And just like with an aquarium heater, using a thermometer ensures that your tank is as cool as a sea cucumber.
Dip into Petco for a wide selection of aquarium heaters and chillers to make your habitat homey for your finned family members.
