of the fish tank is usually related to its size, usually leaving a space of 5-10 centimeters from the top. The reason for not filling the water is to avoid excessive water pressure at the bottom, and if the water level is too high, the fish will easily jump into the tank. It should be noted that the volume of the water in the tank can be calculated according to the water level, so as to facilitate the selection of filtration equipment and ensure that the water can be filtered 7-10 times per hour.
the water in the fish tank 1. Drying: The water used in the fish tank is usually tap water, which is relatively safe after disinfection, but there will also be residual chlorine, which is harmful to the health of the fish, so it is necessary to trap the water by drying, so that the chlorine in the water gradually volatilizes out, thus ensuring the health of the fish.
2. Filtration: After the water is trapped, the next step is to filter it. After the water is injected into the fish tank, it only needs to turn on the filtration equipment, which usually takes three or four hours to filter, so that the water becomes clear, and the suspended particles in the water will be absorbed, thus making it look more beautiful.
3. Oxygen: Fish need to breathe in the water. If the oxygen content in the water is too low, the fish will float and even die. In order to increase the dissolved oxygen, an oxygen pump is needed to pump oxygen into the water. Usually, the oxygen pump can be turned on for 24 hours.
