Coldwater Aquarium Setup

Coldwater aquariums are similar to that of a freshwater tropic aquarium; to the exception of a heater they are practically identical. Both aquariums are filled up with tap water and conditioned, then run for a couple of days till the dechlorination fluid takes effect. Because of the nature of coldwater fish and their digestive behaviour they are naturally messier than tropical fish. When choosing an aquarium it is always worth bearing in mind that the quantity of fish you are likely to keep in a coldwater aquarium is significantly less than that of a tropical. The fish are generally larger than tropical, with larger life expectancy and often a more placid temperament. Although the majority of coldwater fish are typically larger, producing more waste than tropical fish they are naturally more tolerant to fluctuating or poor water quality and are often able to endure these conditions for years, far surpassing even the hardest of tropical fish. In summation although coldwater fish produce more waste and intoxicate their aquarium more than tropical, they are considerably more tolerant to this and are far less susceptible to the problems that often derive from poor water quality. Providing the aquarium you choose has adequate volume and filtration for the stock you intend on keeping then there is no benefit between keeping either tropical or coldwater, the choice lies purely on personal preference.

When setting up any aquarium it is always best to seriously take into account that bigger is always better. The larger an aquarium is the more diluted any toxins produced by the live stock will be. This results in better water quality and a more stable aquarium as the water will take a longer duration to deplete in quality, often caused by overfeeding. This gives vital bacterium more time to develop within the filters to compensate for this momentary rise in pollutants before any problems could occur. This bacterium biologically reduces nitrite and ammonia that are bi products of fish waste, it is inevitable in all aquariums at one time or another. If the aquarium becomes too polluted the water will begin to become toxic. However once the correct bacterial levels have been achieved it will maintain the water quality and in turn produce a more stable aquarium requiring little maintenance for large rewards.

Choosing your new aquarium's location

When you choose a location for your new aquarium in your house it is important to remember the following points:

  • Sunlight will often affect the levels of algae within your aquarium, so try to avoid placing it near windows and skylights. Although natural sunlight can have a positive effect on the aqaurium environment it should be carefully monitored.
  • Try to locate the new aquarium away from sources of noise and vibration. It should not be located next to items such as Cookers, TVs, radios, washing machines and fridges. Fish don't like loud noises and constant exposure to noise will cause stress and adversley affect thier well being.
  • Do not place the aquarium near radiators and fires these will affect the temperature of your aquairum, large fluctuations in temperature will affect your fish health. Most fish need to be kept at a constant temperature.




What do I need to setup a coldwater aquarium?

  1. A filter. This is essential for any aquarium that has a number of fish to maintain clear and healthy water. Although if you only plan to have one or two fish, it is possible to have a perfectly healthy aquarium without a filter, by using the correct planting and water changes.
  2. An airpump, hose and valves. These provide the necessary oxygen for fish and plants, it also helps with the filtration process by aerating the water and adding decorative touch with bubbles to your aquarium.
  3. Lighting. A suitable aquarium light should be switched on for 8-10 hours a day, this will artifically replicate night and day. This is essential for natural plant growth and displays your fish to thier best potential, it can also help minimise stress.
  4. A thermometer. This will help you to keep an eye on the water temperature at all times.
