Having been sitting in a vat over the weekend I half expected there may be an issue with different temperatures as my pond is currently at 21C, after floating it in the bag for half an hour it was released into the pond.
Fourty eight hours later most of my koi are flashing a lot, I scraped three fish half expecting to find whitespot, nothing.
The next evening the fish were going down hill, flashing, head down, claped fins etc and I was tempted to add MG&F without further evidence.
I decided to have one more scrape and was not surprized to find whitespot, only a couple of immature individuals but that confirmed my suspicions.
My second dose of MF&G will go in tonight and all the koi are showing the effects of the whitespot, bar one, the new koi has no symptoms of whitespot whatsoever and is swimming around as happy as larry feeding as normal.
So my query is, is this normal?
