Re: Sump/clarifier size??
I guess it's a matter of degrees and how complicated and expensive you want to get. The short answer is a sump that hold less that the capacity of your extractor is going to result in a faster build up of wax in your holding tank. The bigger the better but no clarifier is going to be perfect. Accept that fact that you will have to, at least occasionally, skim your holding tank. Why not just think of a little wax in your tank as a protective layer, I assume you aren't going to be bottling directly out of it.
