Do you know what level the nitrates are currently? Do you know the normal or desired range in your tank? The high range is easier to use.

My nitrates are always about 5 ppm so I like the high nitrate test kit. I think if you are running an ULN system then need the low

Unless your nitrates are really, really low get the HR. Watch a YouTube video of someone doing a test on the low range. It's insane how involved that test is, compared to the high range where you drop some powder in and shake the vial.
