What aspects of the hobby do you find easy to understand?

[Gumbies R Us]

Usually we talk about what can be difficult or what gives us trouble. However, I wanted to discuss what you find is easy to understand. Maybe it's easy for you to understand where to place coral to where they get the best light and flow, or maybe you understand what livestock should go in your tank. Curious to see what everyone says!

everything except the chemistry portion of it. i cannot for the life of me comprehend how each element works with the next.

we're all privileged to have @Randy Holmes-Farley amongst other very knowledgeable reefers to help with our chemistry questions.
