Really? The last thing I would ever use is a controllable pump on a skimmer. Over complicates things, adds additional cost that doesn't need to be there, and once set, you probably never have to adjust again.
An appropriately matched skimmer/pump set should already be at the right values and the only tweaking should be air volume and water height.

I know I'm old and set in my ways, but adding features for the sake of adding features is not something I buy into.
