What size tank is it and how old is the tank? Have you added any type of additives or chemicals to the tank? Things such as stress remover, medication, red slime remover, chum-clean or water changes using dechlorinators or water conditioners?

Are you running activated carbon?

Yup, that will do it. You need to run carbon to remove any slime remover left in the water. Once that has been removed, the skimmer will go back to normal. If you read the box on the slime remover, it actually states to no run skimmer and then do several water changes to remove any residue of the chemical from your system.
