Betul, On....kalo di daerah Tawakal memang airnya agak sedikit basa shg agak mempengaruhi kecerahan warna KOI-nya. Kalo saya pake air PAM; maka warna KOI-nya bisa kembali lebih ngejreng....gitu lho. Tapi secara umum sich....kondisi air tanah yg saya pake (setelah melewati filterasi) tidaklah berpengaruh banyak kepada kondisi kesehatan ikan KOI saya.
