My mom just showed up a few hours ago with 2 snowflake clownfish and what looks like a zoa coral for my tank as a gift. The problem with this is my tank is only a week old and not cycled yet! I have the fish and coral in their bags floating in the tank so they don't get cold but I just tested my tank and my ammonia is still 1ppm. I called the store she bought them at and asked if they would take them back for credit or quarantine them for me but they won't. A friend of mine suggested a 50% water change and a bottle of nitrifying bacteria. What should I do?!
