TDS Meter Readings

[80gJoe]

I'm "new" with TDS Meters and I'm wondering what is a "normal" reading for a Discus aquarium?

For breeding 80 to 120. For rearing juveniles 100 - 300+?

;D ;D ;D Same ? as above. My 90g tank is at 380ppm, my 125g is 360ppm & a baby tank is kept between 300-350ppms, today reads 350ppms. More important is what minerals are making up the ppms, esp with growing youngsters. & as Carol has said, breeders are much lower. See Nancy's thread above this one, Dottie
