I vouch for Theron's response. You'll be sorry if you don't do both!

This is where I am confused...if the bottom drain will remove anything that
comes to the bottom, why bother having a skimmer? Why not let it fall, rot,
get sucked and become food for the veggie filter?

Cause it makes the process more efficient?

Skimming is an easy way to get a good percentage of the stuff right
away.

It is like why have a door mat, when the vacuum will get all the dirt
once it gets into the carpet?
