Without scientific live fish testing with measurable data points some of these blends might not deliver. One would have to be very careful of how each ingredient used is processed and stored to insure it can be processed by koi. Plus keeping all essential elements needed for health in the proper balance. Without measurable data it becomes subjective observations that may not be correct.
