The reason why water is not injected is to avoid that the water pressure at the bottom is too high and the water level is too high, so that fish can easily jump into the tank.
It should be noted that according to the water level, the volume of water in the cylinder can be calculated, which facilitates the selection of filtering equipment and ensures that water can be filtered 7- 10 times per hour.
First, how high is the water level in the fish tank? The water level of a fish tank is usually related to its size, and it is usually enough to leave a space of 5- 10 cm from the top.
The reason why water is not injected is to avoid that the water pressure at the bottom is too high and the water level is too high, so that fish can easily jump into the tank.
It should be noted that according to the water level, the volume of water in the cylinder can be calculated, which facilitates the selection of filtering equipment and ensures that water can be filtered 7- 10 times per hour.
Second, how to raise fish tank water 1, drying: the water used in fish tanks is generally tap water, which is relatively safe after disinfection, but there will be residual chlorine, which is not good for the health of fish, so it is necessary to trap water by drying, so that the chlorine in the water can gradually evaporate, thus ensuring the health of fish.
2. Filtering: After the water interception is completed, the next step is filtering.
After the fish tank is filled with water, just turn on the filtering 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, which makes 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 or even die.
In order to improve the dissolved oxygen, it is necessary to pump oxygen into the water with an oxygen pump.
Usually the oxygen pump can be turned on for 24 hours.
