Hi

Generally very high, around 1600ppm is reported to be fatal NO3 levels.

I've seen CRS breeding like rabbits in a tank with >160ppm (more than resolution of API test kit) TDS was 500. Not my tank tho.

Due to a pump failure I ran for a couple of days with 400ppm NO3 in my tank. Only noticed when I heard the pump whirring couple of days later. Fish fine, plants fine, no algae just really annoying as emptied 1litre of EI solution and didn't end up with monster plant growth...
