How Can I Make My Fish Tank Water Clear?

To clarify fish tank water: first, let new water sit and dechlorinate, then change 1/4 to 1/3 of the tank water each week. Keep the temperature and pH of the new water close to the tank water to avoid stressing the fish. Second, choose a suitable filter based on tank size and the type and number of fish, and clean the filter media regularly.

Also avoid overfeeding, since leftover food decomposes and produces harmful substances that worsen water quality. Finally, plant an appropriate amount of aquatic plants—they absorb nutrients from the water, help purify it, and provide a better environment for the fish.
