I am using a white labs German lager yeast wlp830. It says to get the fermentation started it should be 70 deg. Do I move it to a cooler location once the fermentation starts?
That’s the way to make a bad lager. Well, maybe not quite, but it’s certainly no way to make a good lager.
The way to make a good lager is to pitch plenty of yeast (twice as much as ales - four vials or a large starter) at proper temperature (46-54°F) and hold it there.
So what your saying is get it to a cooler temp fast?.. Hehehe.
Not sure where you got the 70F, but as above mentioned, 50s is better. This is cut from the WLP web site regarding 830:
