coralline spreading and shrimp molting is a sign that you have a good calcium level. coralline algae is considered a good thing by most. the biggest question....why do you have "fake plants" in your saltwater tank?

If this is the hard crusty coraline algae than it is good
the purple algae is normal, expected and considered good. If you dont like the look you just need to scrap it off of the glass and other items. if you do this in the tank however it may increase it spreading
if this is more of a slimy plant like algae that you can rub off with your hands than it is not so good. probably cynobacteria and means new tank, high nutrients, to much light generally, if its like this let me know ill find the post that explains how to get rid of it for you

I am assuming the purple algea is coaline. If that is the case you are fine. It is a bit unusual to have it going that good so soon. If its not coraline, you are in the middle of what sounds like an algea bloom. This is also the norm on a new tank. As far as the shrimp, that is normal as well.
