    pengaruh ph air kolam yang rendah

    rekan2 koi-s,

    mohon masukannya, kemarin saya cek parameter air kolam hasilnya ph 5,5 dan nitrate 0,5, sedangkan ph air PAM 7,0, kondisi ikan tidak ada masalah atau sehat2 saja, tapi apa pengaruhnya kepada ikan kalau kondisi ph 5,5 berlangsung dalam jangka panjang? hal lain adalah air kolam meskipun bening namun banyak lumut mati melayang sehingga mengganggu pemandangan, apakah lumut mati berhubungan dengan kondisi ph yang rendah itu?

    dan juga saya perhatikan pada satu sisi dinding kolam tampak sebagian lumut hitam menghilang dan muncul lumut baru berwarna hijau(gambar 2), gambar 1 adalah kondisi normal dinding kolam, dimana lumut berwarna coklat

    kalau lumut mati tidak berhubungan dengan ph rendah apakah ada penyebab lain mungkin seperti perubahan musim atau memang karena adanya regenerasi lumut yg normal?

    btw, kolam saya outdoor tanpa shelter, terekspose matahari selama +/- 4 jam (jam 10 - jam14), umur kolam 1 tahun, volume sekitar 11 ton (termasuk filter), penghuni ada 10 ekor (ukuran 12 cm - 60 an cm)

    terimakasih banyak sebelumnya atas masukan rekan2.
    salam
    fredy
