Covering the back wall of your aquarium with moss or plants can be quite a challenge. Here we show you how to do this...
Throughout the year we ensure that the temperature of the aquarium remains at a fixed value. Normally, only heating is required. This works very well with a heating element. As soon as the ambient temperature rises above the set temperature, the control is gone. Concerns about the rising temperature of the aquarium water often increase at the same rate...
All plants and animals are programmed in their DNA to feel comfortable at a certain temperature. If the temperature rises above the tolerance values for an extended period of time, they will fail. A task for the caregiver to take measures and prevent suffering.
Let's not panic right away. In nature there are also periods of heat and warmer days. As mentioned, animals and plants have a built-in tolerance for this. Persistent heat is a problem.
Oxygen is much less soluble in warm water. With a lower oxygen concentration, it becomes more difficult for fish to function. This causes more stress, with all its consequences. There are two things you want to do:
1. Control the temperature
2. Ensure that there is sufficient oxygen available
Heat is required for evaporation. Our body, for example, releases moisture (sweat). Air passing over the moisture extracts heat, which cools our body. A dog does that with his tongue. With a wet T-shirt on it goes even faster and with a fan above it even faster. We can apply both principles to the aquarium:
- Place a fan on the surface of the water so that water can evaporate. For example with a Hobby Aqua Cooler or aFAN aquarium cooling fan.
- Leave the light hood/valve covers open to allow water to evaporate
- Cover the aquarium with wet cloths, so that heat can be extracted from the outside of the aquarium. With a fan, it goes even faster.
Always keep an eye on the water level and top it up when it gets too low.
The most obvious is to cool the aquarium with something cold. Ice cubes? A frozen soda bottle? A mobile air conditioner next to it? All fun, but not without risk. When ice cubes or a frozen bottle float in the aquarium, fish can nibble on them. Their lips can be damaged in the process. Add an extra barrier such as a colander or some filter bags or something else that will prevent fish from coming into contact with the ice. Maybe ice cubes fit in your filter? Other creative solutions are also possible. For example, by placing the filter in a tub with ice. Or use a longer filter hose and divert it through a container of cold water or ice.
Try to take as many measures as possible to limit the temperature rise. Here are a few examples:
- Make sure the room stays cool. Use window coverings (curtains, screens, blinds, newspapers, etc.). Use a fan or air conditioner.
- Check heat sources. Lighting is a great source of heat. Try to dim if you can. Maybe an hour less or move the lighting period to a later time of the day. The hottest moment of the day is then not enhanced by the heat of the lamps. Is there other equipment in the house or around the aquarium that can be turned off? Then see if that works. Every little bit can help.
When the fish hover at the surface and even gasp for air, this is a sign that action needs to be taken. With an air pump and bubble stone, extra oxygen can be introduced into the aquarium. Other methods are to get the water surface more moving. For example, by directing the outflow of the filter differently or by letting it rise slightly above the water.
Fish are cold-blooded animals. Processes in their body function on the basis of temperature. A warmer temperature increases the metabolism of fish, bacteria and plants. They will move more, eat more, excrete more waste. It is obvious to feed them a little more. As a result, more water will have to be changed on the other side.
Plants will also grow faster. This will have an impact on the consumption of plant food and CO2, resulting in more pruning. Avoid large fluctuations, as this can also cause stress or promote algae growth.
- Take measures to prevent the temperature from rising. Both in the aquarium and around it.
- Add extra oxygen using an air pump and air stone.
- Keep a close eye on the fish.
- Try to keep your head cool and think logically and don't panic too quickly.
