  • A conductivity of 2000-2500 Siemens per metre? Surely, that many ions in the water would kill all the plants! Seawater is only 5 Siemens per metre.

    Unless your conductivity meter actually measures resistivity, which is measured in Ohms by metre. Or if it's some kind of strange crackpot US customary unit for conductivity...
