Re: [stevie] Salt Replenishment: How much do we add?
[In reply to]
I understand your concern and where you are coming from. First of all, are you aware that the salt level in kois are 0.1% level. If salt is 0 level in your pond, then water will flow from the pond into the kois through their skin. This situation will make a sick koi to work harder to get rid of the excess water in their body, if not the koi will be blotted. This is also the reason why we hobbyist use this magic number of 0.1% salt level for our pond water, apart from salt being able to kill certain parasites and bacteria at this level.
Another example is that when your kois have ulcers and you need to use medication that contain Fomaldehyde, any salt content higher than 0.05% will ultimately kill the sick koi. I do not believe that you know this. Fomaldehyde and salt do not mix.
Different salt level kill different parasites and bacteria, hence without the digital salt meter, how would we know what salt level. For example, certain strain of Thricodina needs at least 0.6% salt before they are killed. There are many more examples. Of course prolong salt levels like these are not recommended.
In Japan, some of the breeders used 0.3% salt all the time in the concrete pond as to keep the bad bacteria at bay.
When the situation is OK with my pond and my kois, I too will have 0 salt level in my pond water at times. But history and experienced has shown that having different salt levels with our pond water will keep the pathogen guessing and will not be able to adapt or aclimatize.
So for the serious koi hobbyists, the answer is a yes for a salt meter, it is necessary.
Without a salt meter, we could make errors and as a result, there are more salt in the water then intended. Without a salt meter, we could end up having more salt then expected which will be harmful to the kois. By putting in salt at a correct level, we are not making their habitat and environment similar to the marine set up.
I am animal lover too (e.g. I have 14 stray cats at home that I am providing shelter too!). On the subject matter of ECTHICS which is a debatable subject. A question here is that what make you think that adding controlled levels of salt make it a suffering environment for the kois? With more knowledge and more experience, you will know what salt can do to your kois.
To tell you how serious I am in this hobby, I have all test kits for what ever that I need to perform tests on the water i.e. to ensure the highest water quality for my koi, I have a microscope i.e. to do a mucous swap so that I can determine what bacteria or parasite infection, and I also have a variety of antibiotics injectibles stored in my fridge as a backup just in case I need to inject my precious kois in the event that they are really sick i.e. just like us human.
Let me end this by saying that I am very serious about my koi keeping hobby, I provide the best that I can for my kois in terms of water quality, food and medication. Sometimes I feel guilty that I probably take care of my kois more then my own children. So if you want to throw the ECTHICAL thing here......probably I am not that ecthical here! that I am bias towards my kois then my own children.
Cheers and GOD bless you,
