How to raise water for the first time in a newly bought fish tank?

1. Wash the fish tank with high-concentration potassium permanganate (available in pharmacies) first, and then rinse it with clean water. Then soak it in low concentration potassium permanganate for two days and wash it with clear water.

2. Fill the master cylinder with water, put the water quality stabilizer in the master cylinder, pump the air out of the master cylinder with an air pump, and put the filter material in the bottom cylinder appropriately, thus forming the framework of the independent culture nitrification system in the bottom cylinder.

3. After the filter cylinder runs for 3-5 days, turn on the main cylinder water pump, and stop the operation of the separate small water pump, and you can buy fish back. The fish had better be disinfected before entering the tank.

Extended data:

Regular local water change:

Nitrate cannot be decomposed by nitrifying bacteria, and some removal methods are too expensive. When nitrate accumulates to a certain extent, it will lead to a large number of algae such as Chaetoceros, Phaeocystis, Phagophagous algae and even red algae. This not only affects the beauty of the aquarium, but also does some harm to fish or creatures, thus destroying the ecological balance of the aquarium, leading to flooding and serious consequences.

Therefore, in daily management, it is necessary to change water regularly and 1 0% seawater every month (using sand suction device to pump dirty water under the sand). Pay attention to slowly adding new seawater and pumping it in with a thin tube to avoid the fish being stimulated by the rapid change of water quality.
