I did the reading, and the video watching, prior to starting this hobby. However, I included ‘other’ because the main reason for my success is my LFS - I’ve been well educated first hand using experiences of their 2,500l coral farm set up as well as their display tanks. Such things as ‘fragging lessons’ have been freely given and all questions answered along the way. Living Reef Aquatics, in Dartford UK, has been a phenomenal find for me.
