How to choose an ideal water chiller capacity for your aquarium? It's a matter that is suggested to install the aquarium chiller with power (Hp) more than the recommended. For example, if the specification written the chiller able to cool 500 liters of waters, it should be used for 300 liters of water and so on.
Choosing an ideal chiller for your aquarium will also make your expenses to be efficient. For example, the magnitude chiller 1 / 3 Hp - if we see the price is a bit more expensive than a magnitude 1 / 10 Hp. However, the chiller with a power 1 / 3 Hp has greater strength, so that the unit requires less time to reach the optional temperature. This course will play a major role in maintaining the durability of aquarium chiller units and in general also will reduce noise pollution and the heat generated when the chiller's engine work.

So the best compromise is to keep the aquarium chiller temperature in the save range 23 °C - 26 °C. Although this temperature sometimes also lead the white spot disease for a certain type of fish. However, this is a general temperature range based on the experience of hobbiest and fairly well accepted by most plants and fish both marine and freshwater. No doubt there will be exceptions to some things, such as an aquarium with certain plants which require more stringent temperature tolerance. The best you can do is consults with the experts to know how the tolerance temperature for the aquarium plants.
