It’s Smart To Be Proactive!

The best way to keep your aquarium clean is to maintain good water quality. This will keep your fish strong and vibrant, as well as preventing disease.

How Do I Maintain A Healthy Environment?

It is important to test your aquarium water weekly to verify good quality in addition to a bi-weekly partial water change of no more than 25% to help reduce toxic buildup, remove debris the filter missed, and replenish the oxygen available to fish.

How Do I Take Good Care Of My Aquarium & Fish?

  • Feed & observe fish daily
  • Test water quality weekly
  • Change 25% water every 2 weeks
  • Restore your ecosystem monthly

Feed Your Fish Daily

Feed your fish twice daily with API Fish Food which contains nutritionally enhanced proteins, allowing for easy uptake of nutrients and maximum absorption, resulting in less excrement for clear, clean water. Take time to observe fish to ensure they are active & healthy and be sure to check water temperature.
