But don't raise five, three or two, which is not conducive to the family's money fortune, and will also lead to unnecessary financial ruin and even bankruptcy. Besides the number of goldfish, the color of goldfish is also very important. Generally speaking, blue, gray, black, white and gold have strong effects.
When it comes to fish farming, most of us care about the placement of fish tanks, but we ignore a very important point in fish farming feng shui. This is the number of fish. The number of goldfish has a lot to do with geomantic omen. The number of fish we raise can't just match the family area. In addition to the size of the cylinder, it must also conform to feng shui.
There is such a formula in the book of Hutuluo: "Born with water, the land is 60%. Fire ranks second, 70% a day. There are three trees in the sky, and the ground is 80%. Four places turn into gold, and 90% in ten days. Born on the ground on the 5 th, the ground is 100%. " Therefore, according to the above presumption, as long as we find out the gossip and five elements of the owner, we can know how many goldfish we should keep.
Matters needing attention in changing water in fish tank
1, pay attention to the frequency.
First, pay attention to the frequency of changing water in the fish tank. Don't change water too often, but don't be too lazy. Changing water frequently will cause fish to be stimulated by new water, which will affect their health. Not changing water for a long time will also lead to the aging of water quality and the gradual accumulation of harmful substances, which is also very unfavorable to fish health. Usually, the water should be changed every five to seven days, that is, if the water quality deteriorates rapidly, it should be changed every five or even three days, and if it is well maintained, it can be changed once a week or two.
2. Pay attention to the amount of water.
Besides frequency, we should also pay attention to water quantity. Generally, the amount of water exchanged is one quarter or one fifth of the total amount, and it can't exceed one third at most. In addition, the amount of water is also related to the frequency of changing water. If you change the water frequently, change the water less each time. If the water changing cycle is long, more water should be changed each time to maintain the water quality.
3. Pay attention to the water temperature.
In order to ensure the health of fish, the temperature should be controlled well when changing water to avoid large fluctuations, and the change of water temperature should not exceed 2℃. Usually, before changing the water, you should measure the water temperature in the fish tank, and then add cold water or hot water to the new water according to this water temperature, which can control the water temperature, make the fish adapt better and avoid causing stress reaction.
