Aquarium thermometer on the suction cup thickened, 11 cm

alcohol thermometer for measuring the temperature of water in the aquarium. Dimensions: length 11 cm, width 1.2 cm. The alcohol thermometers installed inside the aquarium are attached to the suction cup, which is already in the kit along with the thermometer. It is necessary to fix the suction cup with a thermometer on a clean flat surface, peeled from plaque, algae and other substances. The presence of substances will not allow the suction cup to fit tightly to the surface of the glass and therefore the thermometer will not be fixed reliably. Subsequently, it may fall off.

to place a thermometer is necessary in an accessible place for visual observation, while not blocking the panorama of the aquarium. It is clear that by enjoying the aquarium you should not see the thermometer, well, or it should at least not interfere, while you should be able to easily control the temperature. In this case, the thermometer should be located in a place where there is a small current of water (for example, next to the sponge), but not close to the heater. It is bad in itself) You will receive the temperature of exactly the water area that may have nothing to do with the total temperature of aquarium water. If you place the thermometer close to the heater, it will show the heater temperature or the temperature of the water heated by the heater. Given that there is a temperature difference between the upper and lower layers of water in the aquarium, place the thermometer in the middle layer of water.
