  1. At my wits end with Nitrites

    Beginner Freshwater Aquarium
    Hi all... I am a new fish tank owner I have a 20 gal tank with 4 zebra danios in it with plants and a piece of drift wood. I have had this tank cycling for about 6 (ish) weeks now. I was taking water to Petsmart almost 3-4 times a week to get it tested until I could afford the API master...

  6. my first cycle, almost through? water change question

    Beginner Freshwater Aquarium
    First off, so happy to have found this forum. I had a tank during middle school while I had chronic migraines and it was a huge part of my life then.
