| Babykoi,
Sorry for the late reply.
I don't own any Shiro utsuri cos have to completely shade my pond and install chillers if I intent to keep any good one. Too heavy on electric bill.
1) Soft tubing type.
2) Ours contain no preservative which is why the expiry date is only about 2 weeks. Once open last only 3 days at the most.
3) The tofu I use are white with no flavouring.
4) IMHO it is not advisable to give soya bean itself for not easily digestible. Tofu are easily digested as it is the extract of the beans. Can feed direct from the packet as it is already cooked during the production process.
5) I'm just speculating that tofu improve the shiroji of my koi. No hard evidents that's why I'm asking members of the board do they have similiar experiences.
6) After 3-5 hrs back wash your filter systems. You'll see lots of tiny tofu 'snow flakes'.
7) Doesn't affect my water parameter. Before & after my TDS still stand at 120-125ppm.
