Today, my artificial wetland fails. But it's not because of usage.
Semalam, atau malam sebelumnya hujan deras. Sepertinya air hujan mengubah kualitas air. Plus, keberadaan kayu apu (Pistia sp.) ngeblok penetrasi oksigen yang kebutuhannya sedang meningkat.
Siang sekitar jam 9, wah, sudah bau. Semua cichlid dan lele kebalik sudah jadi bangkai. Bau. Mujair dan mas gedhe, ketoke diemplok kucing. Soale ning pinggir kolam -untuk kedua kalinya- ada bangkai tikus nganggur.
Yo wis, daripada nunggu airnya bagus dengan aerasi, mending dikuras abis semuanya. Alhamdulillah, sekarang sudah bersih. Tapi ikannya abis, tinggak 2 sepat, 1 sapu2 dan kira2 40 ekor zebra pink.
Semua kayu apu dipindah ke bak kompos yang salah satunya mengandung bangkai tikusyang bentuk kehidupannya sudah berganti. Kayu apu ditinggalkan sedikit di ujung pembuangan deket settling seperti waktu pertama dikembangkan dulu...
Masih nyari tahu gimana memanfaatkan atau mengontrol pertumbuhan kayu apu dengan musuh alaminya. Mungkin remis atau keong mas will work...

Oil slick
It's difficult to treat slicks of vegetable oil spilled from kitchen sinks. If possible, it should be contained in pretreatment pond. Emulsification and decomposition seems practical but but takes longer than visually expected. Well, it's not nice to see slick over a pond that is meant to entertain tired eyes after day work.
Spraying some diluted detergent has been done, but further experiments on its dosage would reveal what's going on.
To note, small amount of detergent in the pond, even a small amount of it change the water green so much.
