AnswerDear Dolores,
Sorry to hear you are losing koi.
After the winter koi are weak and in that case also open to bacteria, diseases etc.
The redness is mostly from stress however from A distance it is hard to tell which is the case.
We normally monitor the koi with following list:
1) waterquality (PH, GH, KH? ammonia, nitrite,...)
2) check if it is only one koi or more
3) visual signs
4) scrapes with microscope to check parasites.
So it is hard to tell which is the case of death.
Best way is to take the koi when its still alive to the dealer to check or call A vetrenarian.
When you want to use salt,some people are pro some not, this mostly is from 0.1 to 0.3% salt.
This means you need to measure the pond.
for 1 liter you need to add: 0.1 to 0.3% salt
I think 13000 gallons = 49210 Liter
Than, if this is the case you can add:
So 0.1 / 100liter = 49.2kg
However personally I would advice first to test the water and ask A local expert to ensure the best treatment in this case.
Kind regards and much luck,
Raf
