One koi flashed a few days ago. There are 5 koi in the pond. I add salt to .3% over 3 days(.1% per day) and then add Supaverm on the third day. Now all the koi are not eating. They were eating normal before the Supaverm. Is this a normal reaction to the Supaverm? First time use Supaverm. Water parameters are fine: 0 Ammonia 0 Nitrite, 0 nitrate. 7.8 PH, and low KH(2 drops) and plenty of air.
Any help will be greatly appreciated!
