I have recently had a nitrate and nitrite spike in my shrimp tank.
Ammonia at 0
Nitrites at 1ppm
nitrates 30ppm.
what would be more harmful for the shrimp, a large water change getting out more or doing a small water change thus leaving more nitrite and nitrate?

I would do moderate water changes (maybe up to double your usual change, whatever that may be) every couple of days. How much do you usually change every week?

I was only doing 10-15% a week

You could probably do 20%, maybe 25%. Obviously, be cautious with things like temperature and dechlorination. The key might be doing changes of that size more frequently until the blip is over. Additionally/alternatively, what's your plant situation in this tank? Increasing plant population could help your nitrogen numbers.

I'd bump the amount up a little and do them daily until you get those nitrites down.
