| In regard to dramatic pH differences.... A 12-hour or less cross-country flight does not seem to cause that much of a differential for a single koi or a couple of small ones in a bag. A 24-hour or longer travel time for bags stuffed with 50-100 tosai are another thing. One dealer in the eastern U.S. who suffered significant losses in acclimating such mass imports found pH differentials to be very material. Shipment water could be down to pH 4.5. By adjusting the receiving water to a pH of 5.5, the losses ended. The pH was allowed to rise gradually over a period of several days. This not something to do without taking measurements, understanding your water and monitoring conditions carefully. Like so many things, an idea may be good, but result in even more problems, unless there is a real understanding of how all the pieces and parts fit together. |
