To baffle or not to baffle?

[sphelps]

On my last 100 gal tank I just had an open tank for a sump with just a skimmer, no baffles at all. I used a herbie style drain and didn't get any bubbles at all. It's important that your skimmer also doesn't allow air bubbles to exit otherwise a baffle or something may be require for that. Provided you don't have any source of air bubbles and don't require specific water direction travel baffles serve little purpose.

I did it mainly for simplicity and laziness but it would certainly give more flexibility for equipment changes/additions. You could also build removable baffles very easily.
