Diatoms and green algae is going away and some purple stuff is showing up on glass

I can see where it might look like coralline algae, but it looks more like diatoms and some cyano to me. Will it wipe off easily? Coralline is a hard plating calcerous algae, if it wipes off easily it's not coralline.

True but cyno doesnt typically grow on the glass

Unless it wipes off easily, then it's not.

Ok I tried to wipe it off the green comes of with one swipe of the mag float but it takes four or 5 swipes for that to come off.

Yep coralline algae. If it was cyano it would wipe off just as easily as the green stuff.
