Use one pump for return/ skimmer

[Saltar]

I was wondering if it is possible to feed my skimmer by Plumbing off my return pump? If so how do I get air into the skimmer?

Some skimmers are made to run off of a feed pump but need a recirculating pump with a air line fitting. I'm no expert in skimmers but I don't think it can be done on just the return pump.
