Small Tips Of The Fish Tank Water Change
Why do fish tanks need to be changed frequently?
Reasons for changing water (1)
Water quality can be improved by changing the water. Organic matter such as fish manure and food residues will produce toxic substances such as ammonia nitrogen compounds and nitrites. Nitrifying bacteria can convert ammonia into nitrites and nitrates, which are then converted into nitrogen compounds by anaerobic bacteria. . But the conversion and decomposition requires speed, which is far behind the excretion speed of fish and the speed of your feeding, so when your fish tank has not changed the water for a while, although the nitrification system is still working, the ammonia in the water, nitrous The nitrate concentration must also exceed the standard, and a direct water change can quickly and effectively dilute this concentration.
Reasons for changing the water (2)
Changing the water can stimulate fish growth, activate the fish’s immune system, and speed up metabolism.
How often to change the water and how much is correct each time? The general water change amount is not more than one-third each time, and the time period is 2 times a week in summer. Once a week in spring, autumn and winter, because the temperature in summer is high, the bacteria in the water are active, and the water temperature can be above 30 degrees without a heating rod, and the naturally occurring corruption reaction is fast. Corruption occurs.
Generally speaking, it is not recommended to change the water in the first month of the newly opened fish tank. Because our main purpose for the first month is to hope that the water quality of the fish tank will stabilize as soon as possible, so do not change the water too frequently. Otherwise, the water quality of this fish tank will be difficult to stabilize, so the state of the ornamental fish in it will also be difficult to stabilize. Therefore, it is best not to change the water in the first month of opening the tank. Unless there are some special circumstances, such as accidentally adding some drugs, the water quality of the fish tank has been seriously affected.
Then, after the fish tank is opened, if our ornamental fish stocking density is moderate. Then, the water is usually changed once a week, because after the water quality stabilized last month, basically everyone can already see some brown algae on the walls of the fish tank. And when we touch the walls of the fish tank with our fingers, we can also feel the slippery feeling, which indicates that some probiotics, such as nitrifying bacteria, have stabilized in the water body of the fish tank. At this time, we keep changing the water once a week, and it is very necessary to change the amount of 1/3~1/4 each time.
