Hi Janean. To answer your question of what is the best way to learn is to join the group Aquaponics for beginners and any other groups that you may be interested in. Don't be shy. Just start asking questions and I can pretty much guarantee that someone on this site has the answer. Start small and learn all you can and let it grow... skys the limit. My setup is small by comparison to some other systems and I have a variety of Goldfish that are getting pretty big and are loads of fun to watch and feed. I have a 6 year old boy who loves to put his hands in and let them nibble. We've grown string beans, cukes, spinach, herbs and lettuce. I can't grow enough to feed my family but I will say that it's really cool to tell people that we're eating fresh out of the garden veggies when it is 0 degrees  outside and a foot of snow on the ground. I get puzzled looks when I tell them that I have a garden in my basement. Take care and enjoy this site. Drop me a line once in a while to say Hi...
