is the difference between new water and old water? If you want to know better what kind of water the fish likes to live in, you need to find out the difference between old water and new water.
1, old water: After a period of drying, and in the fish tank to receive a very sufficient light. And in the process, the water is constantly flowing. The water is clear and light green, and there are many microorganisms and algae that are good for fish, and the humus in it is also good for fish growth.
2. Fresh water: Fresh water often refers to tap water that has been dried for 2-3 days. It can also be very fresh and clean well water. Such water is very pure, and there is no complete colony of nitrifying bacteria in the water, which does not meet the requirements of some fish for their living environment.
. Silver arowana is a kind of mild fish in osteoglossus. It likes quiet and likes old water. Old water can provide some beneficial microorganisms for the growth of silver arowana, and some algae in the water can also become their food. A more stable circulation system in old water can lay a good foundation for their healthy growth. In such water, they can grow fatter. However, there is very little humus in the new water, and there is no nitrifying bacteria colony in the water to maintain the stable circulation of the water environment, which can not provide a healthy growth environment for the silver arowana. So they generally prefer old water.
do silver arowana like? They prefer to live in soft water with weak acidity. The acidity and alkalinity of water can meet their growth needs between 6 and 8. In order to keep them active, it is better to keep the pH of water between 6.5 and 7.5 at home. This kind of fish prefers soft water, and it is better for breeders to control the hardness of water between 3 and 12. If the hardness of the water exceeds this range, it may adversely affect their normal growth.
