Wah, di milis ini ada penggemar grass rock ya... :D Kesadahan artinya kandungan mineral-mineral di dalam air... "keras" maksudnya kandungan mineralnya tinggi. "Lunak", maksudnya sebaliknya, yaitu kandungan mineral-mineral di dalamnya rendah. Mineral-mineral yang dimaksud adalah ion-ion logam, paling umum adalah Ca dan Mg, bisa juga ion logam-logam lain maupun garam bikarbonat dan sulfat.

Berhubung bukan ahli perikanan saya justru bingung dengan istilah : PH & Kesadahan (misalnya kesadahan lunak). Kalau PH sih dikit2 tau maksudnya, tapi kesadahan apa ya..??? Mohon pencerahan dr para senior. Terimakasih. ..& salam metal... [Non-text portions of this message have been removed] Yahoo!
