1. Daily Checks

• Observe the fish’s behavior, appetite, and overall appearance.

• Remove any excess food, dead leaves, or visible debris from the bottom.

• Check whether the equipment (heater, filter, air stone) is functioning properly.

1. Weekly Cleaning and Water Changes

• Replace 20–30% of the aquarium water.

• Perform gravel vacuuming, especially in areas where food residues and waste accumulate.

• Clean algae on the glass with a magnetic scraper or sponge.

• Rinse filter sponges gently in aquarium water only; avoid tap water.

• Trim plants with yellowing or decaying leaves.

1. Monthly or Bi-Monthly Maintenance

• Check all filter media (ceramics, floss, etc.) and replace if necessary.

• Clean the aquarium cover and lighting fixtures.

• Test water parameters such as pH, ammonia, nitrite, and nitrate.

1. Things to Keep in Mind During Cleaning

• Avoid sudden movements that could stress the fish.

• Ensure there is no temperature difference when adding new water.

• Never add tap water directly—always use a dechlorinator.

• Use equipment dedicated only for aquarium cleaning; never expose it to detergents or chemicals.

1. Factors That Affect Cleaning Frequency

• Aquarium size (smaller tanks get dirty faster).

• Fish type and stocking level (crowded tanks need more frequent cleaning).

• Filter type and efficiency.

• Plant density and feeding routine.

Conclusion
Regular cleaning and maintenance help stabilize water quality, keeping fish healthier and more active. Cleaning is not just for aesthetics but also for maintaining the biological balance. With a simple yet consistent routine, you can provide a stable, long-term environment for your aquarium inhabitants.
