When raising arowana, it is normal to keep the pH value between 6.5 and 7.5, the hardness of the water should be between 3 and 12, and the temperature should be maintained at about 24 to 28 degrees. Arowana is very sensitive to changes in water quality. When changing the water for it, just change one-third of the water at a time. It is difficult to raise arowana, but as long as the water quality is kept stable, you can avoid getting sick.

The high pH value of water has an impact on arowana:

If the pH is too high, it will lead to arowana poisoning, reduced resistance, and easy disease. Well, some aquarists will think that when the pH is not between 6.5-7.5, they can just quickly adjust the pH to the appropriate range and then they can sit back and relax. In fact, this is not the case. Experiments have proved that when the arowana is between pH6-9, it will not It will affect the growth of arowana, and a violently oscillating PH, such as rising directly from 6 to 7, although the change is only 1, is a rapid change in PH for the arowana, which will make the arowana seriously unsuitable.

The impact of pH value on fish

1. The pH value range suitable for aquaculture is between 7.5-8.4. If the pH value is lower than 7, the water body will appear Acidity will irritate the gills of fish, causing the oxygen-carrying capacity of the fish's blood to decrease, affecting the fish's breathing, resulting in a decline in the fish's physical fitness and reduced resistance. It will also affect various physical and chemical indicators in the water body, such as the production of toxic and harmful substances such as hydrogen sulfide.

2. If the pH value of the water body is too high, the proportion of ammonia nitrogen in the form of molecular ammonia in the water body will increase significantly. When the pH value of the pond is greater than 9.0, the content of molecular ammonia will be greater than 35%, which will increase Ammonia nitrogen toxicity in ponds eventually causes ammonia nitrogen poisoning in pond fish.
