The figures we use in fishkeeping are ppm of calcium carbonate or German degrees. Your water is very hard and the only tetra I can come up with that can cope with it is the X-Ray Tetra, Pristella maxillaris. Have a look here for more about them and some pictures: https://www.seriouslyfish.com/species/pristella-maxillaris/
