Aquarium issues can arise, but most are easy to fix with the right approach. Here’s how to address common problems:

1. Algae Overgrowth

   • Reduce lighting duration to 8-10 hours daily.

   • Add algae-eating fish like plecos or snails.

   • Avoid overfeeding to limit nutrient build-up.

2. Cloudy Water

   • Caused by bacterial blooms or debris.

   • Perform partial water changes and ensure proper filtration.

   • Avoid overstocking or overfeeding.

3. Stress in Fish

   • Symptoms include rapid breathing, hiding, or erratic swimming.

   • Check water parameters and maintain consistent temperature.

   • Provide hiding spots and reduce tank activity.

4. Ammonia Spikes

   • Often occurs in new tanks or after adding too many fish.

   • Perform immediate water changes and use ammonia-removing products.

5. Fish Diseases

   • Common issues include ich, fin rot, and fungal infections.

   • Quarantine sick fish and use appropriate medications.

6. Filter Malfunctions

   • Clean filters monthly to prevent clogging.

   • Ensure proper flow rate and replace worn-out parts.

7. Heater Issues

   • Use a reliable, adjustable heater with a built-in thermostat.

   • Monitor tank temperature daily.

8. Low Oxygen Levels

   • Add an air stone or increase surface agitation.

   • Avoid overcrowding and overfeeding.

9. Unwanted Pests

   • Snails or planaria can appear from live plants or overfeeding.

   • Remove pests manually and reduce feeding.

10. pH Fluctuations

    • Stabilize pH by using a buffer or regular water changes.

    • Avoid drastic changes, which stress fish.
