To come up with a realistic aquarium set-up, a fish keeping hobbyist has to take note of the various characteristics of the marine world they want to replicate. If it is a freshwater set-up they should take into consideration the fishes and accessories that should be included. More fishes and accessories in a set-up means that the aquarium should have a good filtration system in order to support the entire artificial aquatic life. It is more complicated in a salt water aquarium. This is because the water in these aquarium setups should be maintained in ranges fro 22-30 degrees centigrade (71-86 degree farenheit). These are the ideal temperatures to sustain fish and plant life in salt water or even in tropical freshwaters.battery powered fish heater
To be able to maintain the proper temperature in an artificial aquatic environment like an aquarium, installing an aquarium heater is highly suggested. There are a wide range of aquarium heaters available in the market nowadays. The most common is the glass immersion heater which has a glass tube containing a heating element. This kind of heater is fully submersible and can maintain the desired water temperature through an adjustable thermostat. This is the latest trend in heating aquarium set-ups as there are thermostat available in the market which are already using advance microchip technology. Microchip controlled heaters have a pilot lamp indicator to indicate the proper temperature. This a far cry to the thermostat of the past which uses a bimetallic strip to heat the water. Other water heaters that are also used by hobbyists are the under gravel heaters and heating mats that are placed under the aquarium tank.
