Water

Our Discus are raised in water with following parameters :
General hardness : 15 GH (dH) – 26 TH(dF) – 270 ppm(mg/l)
Carbonate hardness : 8 KH – 14 TAC – 143 ppm(mg/l)
pH 7
Conductivity : 800 µS
Temperature : 30 °C / 86 °Fahrenheit

If your water is not exactly the same characteristics it does not matter, they acclimate to it.
They accept water with the following parameters:
General hardness :  0-30 GH (dH) /  0-55 TH(dF) / 0 – 535 ppm(mg/l)
Carbonate hardness :  0-25 KH /  0-45 TAC / 0-445 ppm(mg/l)
pH 4.0-8.3
Conductivity : 150-1200 µs
Temperature : 28-30°C / 83-86 °Fahrenheit

Always wash your hands with rubbing alcohol 70% and rinse with water before touching water fish.
