in winter? Tropical fish should also change water in winter as usual, once every seven days. Because this kind of fish needs to be kept at a constant temperature with a heating rod, although the room temperature is low in winter, the water temperature will not change, and the cycle of changing water will not change. Usually, the water for tropical fish must be trapped in advance, so that there will be no chlorine in the water, thus ensuring the safety of the fish. In addition, pay attention to the temperature when changing water.
for it 1. Frequency of water: Tropical fish usually change water once every seven days. Because the water temperature is often relatively high, so the fish will be very active, appetite is also relatively strong, eat more and pull more, so the change of water must keep up, otherwise the water quality will deteriorate, which is very harmful to the health of the fish. Each change of water is generally about one quarter, not more than one third of the total amount.
2. Method of changing water: The methods of changing water for fish are similar. Generally, the old water should be pumped out of the tank before new water can be injected into it. Pumps are usually used to pump water, but siphoning can also be used manually to pump water out. When pumping water, it should start from the bottom of the water to facilitate the cleaning of the dirt inside.
3. Maintain the water temperature: Tropical fish have high requirements for temperature, so the control of water temperature is also very important. It is better to ensure that the temperature is consistent before and after changing the water, and there can be very little difference, but if the temperature difference is too large, it will not work.
