HEATING

There are many factors that have to be controlled in a saltwater aquarium and while many people focus on salinity or pH one of the most fundamental issues is water temperature. There are two elements to a temperature that can be controlled in a tank…heating and cooling. Devices exist to control both issues.

 One of the biggest problems with any tank is fluctuations. Many species adapt to various conditions. However, if those conditions fluctuate than these species become stressed making them vulnerable to a variety of ailments and diseases. Many factors affect the water temperature. Regular 25% water changes can alter water temps as can proximity to direct sunlight, room heaters or open windows.

SALTWATER AQUARIUMS HEATERS 

 Surprisingly not all of the water in the tank is the same temperature. In fact, fluctuations can occur from one part of the tank to another. Water heaters have many mounting options. It is important to place your heater near or in the path of filter intakes or outtakes. We prefer intakes because the flow of water into the filter is often times more gentle than the outflow areas. In either case having flowing water in the path of the heater assures the tank owner that the likelihood of uneven distribution of temperatures is kept to a minimum.

 Very important is to keep the temps warm enough to prevent diseases that are directly caused by cold water. Many tank owners have lost fish populations to common Ichthyophthirius multifiliis which could easily be prevented by having correct water temps. In fact that particular disease can be cured by raising tank temperatures.

 Finally, it is worth noting that some tanks become overheated and although a good heater will shut off it will NOT cool down the tank. Some causes of overheating are direct sunlight and lights such as metal halide which throw off a great deal of heat. To learn more about this issue see our cooling systems.
