Quick Start -- feedback?

In an attempt to make the app more approachable for average pool owners, I want to make it as easy as possible to get started. Currently, users have to make too many decisions:

  1. pool-name
  2. volume
  3. water-type
  4. wall-type
  5. formula

What’s the least we could possibly do? I think it’s something like:

  1. Water-type
  2. Wall-type
  3. Volume

Then, we’ll automatically pick a formula (based on water-type) and an auto-generate a name… but I’m not sure if we could make it even easier. Any feedback is welcome!
