First, apply the Methylene Blue treatment to address Ich, fungus, or other concerns. Then, after completing the treatment and performing a partial water change, add the Nitrifying Bacteria to restore the beneficial bacteria colonies that may have been disrupted during the treatment phase.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this aquarium care kit safe for Betta fish and Goldfish?\u003c\/h4\u003e\n\u003cp\u003eA: Yes!

This is a cosmetic effect and does not affect the health of your fish.
