[HenryC]

After drying off a little and some warm soup and sandwiches, it was back out to harvest another sansai pond. This pond was a sumi machine. Many of the Koi developed significant amounts of deep lacquer black sumi. I asked Mat if there was anything different about this pond. He indicated it was one of the last to be built and since it is intended for growing nisai to sansai (versus fry and tosai), he used much less top soil and mostly bentinite clay in this pond (fry ponds need more top soil to develop the daphina for the fry to feed on).
