In the aquarium feeding process, temperature is a problem that we should take seriously. Fish are variable temperature animals, so the body temperature of fish changes with the change of water temperature. Besides, photosynthesis of water plants, some self-purification function of microorganisms, also need to be carried out at a certain temperature, so we have to give the fish or aquascape of a stable temperature, they can be suitable for making a successful aquarium.
The importance of heater
The concentration of dissolved oxygen in the water is also related to the temperature, the temperature increases, the oxygen capacity in the water will decrease. So if in summer, let the water temperature in the tank increases, the oxygen content in the water decreases, the fish will be hypoxic.We will see the fish often float their heads in the water, the mouth keeps closing, long-term hypoxia fish will produce all kinds of diseases or die.
If the water temperature decreases in winter, it will affect the appetite of fish and slow down the growth. At the same time, not the higher the water temperature the faster the reproduction of parasitic microorganisms in the water, some specific parasites will also multiply at low temperatures, causing water pollution and making fish sick, such as cucumberworm disease.
Other aspects, if we can not do the appropriate water temperature environment, it also has an impact on the reproduction of fish. Fish generally begin to ovulate at about 18 ℃, this is also normal, after all, in too high or too low in the environment of the fish themselves have little appetite, low metabolism in the body, the heat of dizziness, or freezing shivering, bad food, bad water, which think about effects reproduction offspring.
Water & fish
In addition, the sudden change in temperature will also lead to the flow of water, such as the original water in the lower layer suddenly ran to the top, which is a more serious problem. Because we know that the fish excrement, or eat leftovers, corruption, will be sunk in the bottom, is generally fine, because the fish are also very smart, will not find their own disgust to play at the bottom. But if the sudden change in temperature will there be a problem, the bottom of the water to the top Flow, the bottom of these disgusting things up. If your fish encounter these things, can still grow happily?
So the above so much, just want to explain one thing, water temperature is very important to the growth of fish. So we should always pay attention to the change of water temperature, it can be equipped with a thermometer on the tank, or natural feeling. The day is cold to warm up, the day is hot to cool down naturally, etc.. There are many ways to control the water temperature, such as using temperature control facilities, etc.
Style of fish tank heater
Heater is the most commonly used aquarium supply used for aquarium water heating, according to its principle and structure can be divided into two categories, one is electronic, using thermistor detection control temperature, the other is bimetal mechanical temperature control fish tank water heater. Generally about two years to replace once.
Fish tank heater selection principle is as big as possible, because the big will save some electricity, it is also a kind of protection. If you choose a small heater, it will save electricity on the surface. But in fact, it needs to work all the time and can’t reach the preset temperature. It is working overload, while the high power heater. On the surface, it costs electricity, but it works for a short time, and it can keep the tank temperature well, so the life is long. So the principle of choosing aquarium heater is as big as possible.
What should I pay attention to when choosing a heater?
Tropical fish will also be much more demanding than cold water fish, such as the water temperature, the most adaptable temperature of tropical fish is about 27℃, and the maintenance of this temperature needs to be done by the heater.
Nowadays, aquarium heater manufacturing technology has been very mature, many of the aquarium brands are very good quality. From the power of 50W to 1000W basically have, and more commonly used 100W, 200W, 300W and so on. To choose how high power heater, you need to calculate according to the size of your water body. Such as a liter of water is generally calculated by 1.5W-2W. The size of the power, big is a waste of cost, small is not enough, to do the appropriate best.
Heaters are generally available in two types, one temperature controlled and one non-temperature controlled. The non-temperature-controlled heater must be used only when there is a thermometer. The temperature-controlled heater is relatively more convenient, accurate temperature control and timely heating. It is worth mentioning that the price gap is large, you can choose according to their own situation.
The material of heater is mainly made of quartz and PTC, and some of them have the function of power off from water. Quartz material can be used for freshwater tanks, PTC seawater tanks are not recommended. But PTC is double number display, it looks more intuitive.
The water heater in the fish tank, in the purchase of the original should be so choose.
Now you should know
The water temperature of the water body is related to the environment of the whole fish tank. As long as you keep not cold water fish, the tank water heater is definitely need to be equipped.
Choose the right power heater and other equipment according to the size of your fish tank. And also reduce the amount of water in the tank in winter, to reduce the amount of electricity needed to maintain the water temperature. In addition, you can also add a cover or wrap the fish tank, to reduce the heat exchange between the tank and the outside world.
