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.

Game changer for dying betta
5 Stars
Game changer for dying betta
For the last two weeks my betta has been lethargic and looked dead at times. I tried so many things but nothing worked until this product and also taking the filter out of his 3 gallon tank. Within 12 hours of adding new water (only partial) has been a game changer turn around. Hes swimming around again and in fact, looks so much better. I would recommend this to everyone!
Thank you for your feedback
