Getting the Right Aquarium Heater for your Tropical Fish Tank
Lee Dobbins

A key piece of equipment necessary in every tropical fish tank is the
aquarium heater. Tropical fish are used to warm temperatures in many
species will not survive unless a heater is president in the aquarium
to warm the water up to their native temperatures.

When choosing a heater for your fish tank, it's important to get a good
reliable unit since fluctuations in temperature can be fatal to fish.
You'll need to about 5 Watts of heater or for each gallon of aquarium
water so a 20 gallon aquarium would need a 100 Watt heater. for large

in case the one you are using breaks. This way your fish will not have
