    Overdosed Dr Tims Ammonia

    Hi All! I currently started cycling my new tank 9-10 days ago using dr tims one and only and dr tims ammonia. Since starting my ammonia has been off the charts!

    Controversial Cycling Method

    So I was talking to another reefer the other day and we got into the topic of cycling methods. When I got into saltwater, my LFS introduced me to a very effective and quick method that is seemingly uncommon.
