How does the heatwave affect the aquarium fish

A “hot” topic-specific to this time of year is the heatwave and how we prevent its effects on our pets. Few realize that in homes without air conditioning systems and fish can suffer during the heatwave like mammals and birds.

How do we know if the fish is suffering from the heat?

Simple. The first symptom is that the fish is swimming on the surface desperately trying to breathe. The phenomenon is the following – on the one hand, from hot water oxygen diffuses much faster in the atmosphere, on the other hand, increasing temperature increases the metabolism of fish and thus increases the rate at which it breathes and consumes oxygen from water faster.

What steps can we take to prevent this?

First of all, we should find out about the optimal physicochemical parameters for the life of our fish. Knowing this, we notice that most of the species sold on our market have an optimal temperature range between 24 and 27 ° C. Beyond this area, fish begin to suffer. However, there are several species (such as discussions) for which the optimum temperature is in the range of 28-31 ° C.

How do we counteract this phenomenon?

There are several ways we can counteract the effects of heatwaves in the aquarium. First of all, we must make sure that we do not have a very large number of fish and that the water is changed in time. If the water is properly filtered, the current that forms in the water helps to dissipate heat from the upper layers of the aquarium, to eliminate carbon dioxide and absorb oxygen in the water.

If necessary, we can supplement with an air pump which, in addition to the oxygen it introduces, also helps to mix the water layers.

A common method is to use bottles of ice water. This method should only be used as a last resort, and the temperature should be constantly monitored. Cooling should not be sudden. Sudden temperature fluctuations in short periods can be more harmful than the heat wave itself.

The most convenient method is to use a fan. First of all, you have to give up the lid of the aquarium that stores heat on the surface of the water and does not allow air to circulate. Then position the fan above the aquarium. Ventilation removes air saturated with vapors above the aquarium and accelerates evaporation.

Evaporation is a phenomenon that occurs with heat release. This heat loss can be 2-3 ° C enough to exceed the critical point.

A professional method is to use special coolers for aquaristics.

Careful! After evaporation it is necessary to fill the aquarium water more often. This addition does not take the place of water exchange!

The least used method, but the most effective is the use of a chiller. This is a computer-controlled cooling equipment that helps us stabilize the water temperature to a desired value.

If the temperature fluctuations are not sudden the fish can adapt naturally. In addition, this summer period can be considered as a period of prevention of diseases, especially parasitosis because these pathogens are also affected when the temperature rises.

In conclusion…

If we know how to manage the problem we can turn the heatwave from a negative thing into a weapon against diseases.
