Hello, since two months i swapped from 100% tap water to 75% rain water (15 ppm) and 20-25% tap water ( 240 ppm, GH 17, KH 11), i change 50% of water every week, how is that possible the tds show me 300 ppm (calibrated tds meter) ?
i have no rock in the tank, just plants and sand
I dose EI (magnesium, no calcium) but it seems insanely high for soft water, where does all of that come from ? thx
