Results: Freshwater
Australia is the home of many rainbow fish and therefore very interesting for us aquarists! Our research team analysed every water where fish or plants were to be found. A mere glance at the salt content (conductivity) showed the adaptability of the rainbow fish: They were to be found in very soft water with only 13 microsiemens as well as in hard water with 5230 microsiemens! Also interesting was that the presence of aquatic plants was never relatable to measurable iron values. Test devices: JBL water tests, Greisinger electronic conductivity meter GLF 100, WinLab lux measuring device with waterproof sensor
