| Dear guys
Would like to add another observation to the equation.
I am also from M'sia. My pond is 20 ton with a 25 ton filtration system. I change 10% water daily. I am running a total of 360W air pump into various places in the pond/filter and I feed my kois 8-9 times (only spirulina) a day. I have 11 kois now ( 3 of 30cm Momotaro Kohaku, 1 55cm Ogata Shiro, 2 60cm Momotaro Kohaku, 1 68cm Momotaro Kohaku, 1 74cm Sakai Kohaku, 1 75cm Sakai Sanke, 1 75cm Marudo Showa and a 76cm Omosaku Shiro Utsuri.). Incidentally my water parameters are very much the same as is mentioned by hudi except that the water temp is more like 28 degC.
My experience is that (?luck, ?koi genetics, ?food, ?water management) I have no problems with hi fading, shiro or sumi development of the various kois that I have. Their shiros are still intact and my utsuris (luckily?) did not develop hi despite the heavy feeding of spirulina. I am not into the science of koi keeping but I would like to think it is koi genetics and water management as at one point or another during my early days of this hobby I did have kois that suffered the same fate as what hudi posted. Any comments?
Thanks. |
