Generally, the tank for raising koi needs to be paved. If the tank is small and there is no spare space to install the filter pump, you can not lay the bottom, because the space is already very small, laying the bottom will only make the space more narrow, which is not conducive to the growth of Koi. If the cylinder is relatively spacious, it can be placed at the bottom. This is not only beautiful, but also can promote the growth of Koi.
When raising koi, you can lay water plants, medical stones, or ceramsite and coral in the fish tank. There are small gaps between the ceramsite and the coral, which can absorb the excrement of the koi. Lay Maifan stone on the bottom of the fish tank to promote the growth of Koi. Therefore, Maifanshi can release trace elements, which can promote the growth of Koi. Aquatic plants can dress up the fish tank and create a realistic natural environment for Koi, which is conducive to the growth of Koi.
If it is a newly raised koi, it needs to change the water two to three times a week. If it is breeding large Koi, a week to change water on this, if the weather is particularly hot, need to increase the number of water changes, about twice a week. It is better to use old water for water exchange, and tap water can be used if there is no old water. After the tap water is aired, it can be used for Koi.
