With many electrical equipments such as filters, pumps and lightings that will keep an aquarium running, it is not surprising that aquariums easily overheat, resulting in the fish, plants, invertebrates or corals suffering or even die if the temperature runs too warm.

It is necessary to have an efficient aquarium chiller in tropical or countries experiencing summer season to do the effective chilling job for the aquariums. As most fish and water living beings come from cold waters in the nature, it will be ideal and perhaps necessary to replicate these conditions with, in most cases, a temperature lower than 30°C. Most will thrive well in the temperature ranging between 22°C to 28°C.

As the water temperature increases, so does the fish metabolism and lower dissolved oxygen levels in the water. The higher the bio-load in an aquarium, the greater the risk that oxygen will become depleted when the water gets warmer. Under increased water temperature condition, fish, invertebrates or corals will suffer.

One of the advantages of using a chiller is the automation of the chilling process that will allow you to go for a holiday and be away from your aquarium without worries. One of the obvious cons would be running a costly chiller will consume more electrical energy which translates to higher electrical bills! The larger the aquarium, the more powerful chiller you will need to do an effective job. So unless you are on a budget, consider manual jobs like using ice-bottles for a start and start saving for that chiller.

When buying a chiller, the aesthetics, quietness, energy consumptions, built, quality and warranty will be one of your considerations besides the budget, in deciding which brand of chiller you will go for. But if you can afford one, you will definitely be making your fish happy.
