How to change Fish Tank water – Aquarium water

As long as aquariums exist, there will be long debates about the usefulness of changing the water or how often it is necessary to change the aquarium water. Although this is rare, some exotic fish owners like to believe that their aquarium functions as a small ecosystem similar to that of nature; and therefore there is no need to change the aquarium water, otherwise; it will damage the aquarium. ‘impoverish.

Why change the water in the aquarium?

In theory, this reasoning could be consistent. In practice, it is not. Whatever its size, remains an artificial system, unable to regenerate naturally by itself. This is because aquariums have not been developed according to evolving standards and do not operate according to them. To ensure good hygiene, it is therefore necessary to clean the aquarium regularly. In the natural environment, the metabolism ensures the regulation of the system: the accumulated waste is transformed into basic components, at the origin of all life. So the cycle can start again. On the contrary, in an aquarium, the metabolic chain is incomplete: some components will remain in their raw state indefinitely. They, therefore, stagnate on the surface and eventually reach high concentrations over time. When the maximum threshold is reached; your fish gives up the ghost – despite having so far shown no signs of weakness.

Change the water in your aquarium: how often?

In general, use the following rule of thumb: the smaller the aquarium and the more fish it contains; the more frequently it will be necessary to partially renew the water. The amount of water to be changed is about 30%, which is roughly one-third of the aquarium contents. By renewing this amount of water every two weeks, you should not have a problem. Except maybe if the quantity you renew is too low. Thus, aquarists with large cichlids native to Lake Malawi can change up to 50% of the water volume every week, since their aquarium is very densely populated.
