Hello - like mentioned earlier in this thread, if you had a build thread, it would be a great place to document your tank - its what I do with my own build thread.
this is the info they gave me when I was new:
One fun way to learn from others and keep a record of your reef aquarium is to create your very own build thread! A build thread is just a thread that tells us about your aquarium and might include photos. You can create your build thread in one of these forums. MEMBER'S AQUARIUMS
Once you have created a build thread then you can get your VERY FIRST USER BADGE! YAY! It's easy to do and I have created a thread that tells you how to do it here: BUILD THREAD BADGE
