I feel like it’s an obvious question, but is it normal to get this nitrate reading from your LFS?
I recently had a high nitrate spike which I’m 95% sure is from over feeding, but I tested the water I recently bought (but had not used).
On one hand, I know zero nitrates isn’t ideal, but should prepared saltwater have any reading before it touches my tank? I also noticed a lot of brown gunk (no idea what it was) at the bottom of the container.
