Thermometer for aquarium which is better

maintenance, care, compatibility

The modern market of products for the maintenance of fish offers several options for thermometers for the aquarium, which differ in the method of temperature measurement, as well as accuracy. But which aquarium thermometer is better?

Internal thermometers are placed directly in the water and give information about changes in its temperature.

The simplest of them is a liquid thermometer for an aquarium, created on the basis of raising or lowering an alcohol column depending on changes in temperature. Such a thermometer is fixed inside the aquarium on a special suction cup.

The advantage is the low price, the disadvantage is some error of indication.

Electronic thermometer for an aquarium with an external remote sensor is different data accuracy, but is more expensive than an alcohol thermometer. In it, the temperature sensor serves as a thermistor, built into a separate sealed capsule.

Due to the ability of the thermistor to quickly change its resistance depending on the temperature, the microprocessor can constantly monitor and process the data coming from such a sensor and display it in digital form on the display.

Such instruments do not require immersion in the aquarium water in order to obtain data on the water temperature. These thermometers do not need to be washed frequently, they do not take up space inside the aquarium and can last for a very long time.

The thermometer sticker for the aquarium works due to the property of special paint to change its color when heated. It is fixed on the outside of the aquarium, and therefore can react to changes in air temperature near an artificial reservoir. This thermometer is also called thermochromic thermometer for an aquarium.

Also, such a thermometer can be found under the name of liquid crystal. Many wonder how to use a liquid crystal thermometer for an aquarium.

So, it should just be glued to the outer wall of the aquarium and monitor changes in temperature.

Aquarium water temperature

Water temperature for aquarium fish

One of the most important parameters of aquarium water is its temperature. Most aquarium fish feel comfortable at a temperature of 22-26 ° C.

But there are fish that prefer a lower or higher temperature.

For example, discus is a heat-loving fish, a comfortable temperature for their maintenance is 28-31 ° C. But the Goldfish family, on the contrary, prefers cooler water at 18-23 ° C.

Thus, speaking of the temperature regime in an aquarium, one should take into account the comfortable temperature parameters for a specific fish. It should also be noted that the temperature of aquarium water directly affects the lifespan of some species of fish.

For example, neons at a temperature of 18 ° C live 4 years, at 22 ° C – 3 years, 27 ° C – 1.5 years.

Perhaps the most important rule for an aquarist is to prevent sudden changes in temperature (2-4 degrees). Such vibrations are extremely harmful.
for fish.

Today, there are virtually no problems with maintaining the temperature regime in an aquarium. Therefore, when on the Internet you come across articles about the Soviet methods of “boiling with a kettle” involuntarily you are touched.

Only one thing is frustrating – after all, articles on this topic are usually looked for and viewed by novices or young aquarists who are so easily confused with unnecessary, unnecessary information.

The nuances covered in this article for an experienced aquarist will not inspire innovation, but beginners will be noticed.

So, to maintain the required temperature regime of aquarium water, you need to buy two things at the pet shop:

1. Thermostat heater.

2. Thermometer with suction cups.

Regarding the temperature control of the heater for the aquarium – it is chosen based on the volume of the aquarium (its power must be appropriate). They fix it, as a rule, on the back wall of the aquarium, near the filter with aeration, so that it is completely immersed in the input. IMPORTANT: when setting the desired temperature on the scale of the thermostat, the first time (6-12 hours) watch the level of heating of the aquarium water.

This is due to the fact that often the scale of the thermostat does not always correspond to the actual temperature of water heating (especially in Chinese thermostats) or the thermostat does not quite fit the volume of the aquarium. Failure to comply with this rule may lead to the fact that in the morning your aquarium may turn into “a pot with a good, elite ear.”

Well, the second thing to which you should pay attention – the heater for the aquarium should be completely immersed in water. Do not allow it to be in the on state in air (in whole or in part).

This will lead to its rapid overheating.

Regarding thermometers for aquarium – here everything is simple! They are:

glass (ordinary)

in the form of a self-adhesive strip thermometers for the aquarium

(I do not recommend. creatively — yes, it is practical — no, especially since this strip “fades” over time);

and electronic thermometers for aquarium $ 12;

When buying a thermometer should pay attention to the quality of suckers. If they are weak – the thermometer will often fall to the ground.

In addition, there are fish that pathologically may not like the thermometer and they will deliberately drop it (I have suffered from these gays blue).

I think that with the heating of aquarium water everything is clear: – set, adjusted and forgot.

Let’s now talk about what to do if the temperature goes over the top (from overheating or “summer in August”). Nowadays, this is also not a problem – the air conditioner will not only cool the room, but also lower the temperature of the water in the aquarium.

Another question is what to do if it is not? Or if you need to urgently lower the temperature? Ice from the refrigerator will come to the rescue.

At one time, I poured water into plastic 2-liter bottles (carefully removing the bottle from the label and glue beforehand) and frozen them in the refrigerator. After lowering them into the aquarium and thereby lowered the temperature of the water to the desired.

This method of lowering the temperature has two minuses: firstly, the frozen bottles and ice heat up quite quickly – they often need to be frozen, and secondly: sudden, frequent temperature drops are poorly tolerated by aquarium fish. If the temperature is “tolerable” it is better not to add an ice bottle.

REMEMBER: PROVIDING A COMFORTABLE AND CONSTANT TEMPERATURE OF AQUARIUM WATER IS THE KEY TO THE HEALTH OF YOUR AQUARIUM FISH.

Depends on the volume of the aquarium. If desired, you can put a second thermometer on the remote wall of the water from the heater.
Your thermometer now shows the highest t °. The longer from heating, the t ° is less.

And in the upper layers, it is higher than in the lower layers.
The difference in t ° may be different. Depends on the amount of water and heater power.

Natasha Dmitrienko (Ryabova)

The thermometer in the aquarium should be placed as far as possible from the heater and in the middle (or lower) layers of water. and it is better to have 2 – one alcohol, as I said, and one sticker near the surface. It often happens that thermostats are set to half a degree, it doesn’t matter!

But do not chase after the high temperature, it is better to set as low as possible (according to the type of fish), then when a disease occurs, it will be possible to improve the treatment effect, or even cure it by simply raising the temperature to 30-32 g C. that the higher the temperature of the water, the less dissolved oxygen in it!
