Here are steps for properly changing water in a planted aquarium.
Prepare new water: fill a clean container with water that matches the temperature and pH of the tank. Dechlorinate the water if necessary.
Turn off equipment: turn off filters and heaters to avoid disturbing plants and other aquatic life during the change.
Remove a portion of the water: use a bucket or siphon to remove a portion of the water. The amount depends on the size of the tank and your desired water change percentage.
Replace with new water: slowly add the prepared new water to the tank.
Restart equipment: once the water change is complete, turn the equipment back on.
Monitor water parameters: regularly check pH, temperature, and nitrate levels after the water change to make sure the tank stays stable and healthy.
Water changes should be done regularly, since they help remove excess nutrients and keep the water fresh and clean. The frequency and amount will depend on the size of the tank, the number of plants and fish, and other factors.
