, the best new tank to raise arowana after a week can change the water, if the water quality is not good, less than a week to immediately change the water. When changing new water, be sure to trap the water, dry the tap water for a few days, and then pour it into the fish tank after completely removing the chlorine, so that it will not pose a threat to the health of the arowana. The amount of water changed each time is determined by the water quality. If the water is turbid, one third of the water will be changed. If the water is relatively clear, one fifth of the water can be changed. The best way to
change water is to pump water from the bottom, so that residual bait and feces can be removed. It should be noted that the core of fish farming is water, not nitrifying bacteria, if the water quality is not good enough to cause the fish to get sick, then the loss outweighs the gain. The nitrification system can be established slowly, but the water quality must be well controlled.
1. The first thing to do for the newly bought fish tank is to disinfect it in order to prevent harmful bacteria from remaining in the tank and causing harm to the health of arowana.
2. After the new water is put into the fish tank, it is best to place it in a low-light environment for two days, and then put a fish into the tank. If the fish in the tank can survive normally, the arowana can be considered.
3. To provide a good environment for fish farming, it is necessary to cultivate a good ecosystem in the fish tank and various beneficial bacteria. They can transform some harmful substances in water, the most common of which is nitrifying bacteria. Pour the prepared culture medicine into the jar, then turn off the light and explode the oxygen. When the water is turbid and clear, you can start to raise the arowana.
