skimming and water chemistry

I just set up my protein skimmer and noticed that my alk and calcium have been going down faster than normal. I was wondering if protein skimmers pull other things besides organics ie: calcium, Mg, iodine, any other trace elements.

They won't pull out calcium or alkalinity at any significant rate. They remove some by removing salt water. The skimmer might be improving water conditions and encouraging calcification.

I think that is possible. The skimmer has already pulled out a lot of gunk. I guess I will just dose more and see if I can catch up with the calcification.
