This may be the most important article / video folks will see this Spring because for a LOT of people with sick fish, SALT at 0.3% may be the fastest and easiest way to limit fish losses AFTER testing the water to make sure it's not as simple as a low pH (ha ha ha)
If it's NOT water quality, maybe it is a parasite and MAYBE you can nail it down with Salt.
Here's how. (Using Salt to Control Parasites and More)
If you are not already familiar with the CYCLE, this is the process by which fish wastes and other debris are broken down by bacteria in an aquatic system. Let’s trace it here.
The Cycle is a short series of bacterial reactions that purify water.
Ammonia is produced by the fish, from gills (75%) and vent (25%).
*Nitrosomonas* bacteria in the gravel break the Ammonia down, *before* it has a chance to accumulate and harm the fish.
This results in the production of Nitrites.
*Nitrobacter*, a second cousin bacteria, breaks down Nitrites into harmless NitrAtes before the Nitrites can accumulate and harm the fish.
The Nitrates are simply plant and algae food. In the presence of phosphates, plants use Nitrates to grow, but without the plants, Nitrates could accumulate and cause sickness (Bloody fins and weakness) in the fish.
So you can see that since Ammonia, Nitrite and eventually Nitrate have hazardous effects on Koi, it is necessary for you to use normal testing procedures to detect these intermediates whenever fish are sick.
The Cycle takes 4-6 weeks to complete under normal circumstances but t’s possible to cut it down to about three days with BioSeeding. That is a technique, not a product. It’s described in this website.
Be sure to see the video on BioSeeding (video) and consider it when rushing the cycle.
Don't forget about the Youtube Channel that supports Koivet.com in the mission to educate (especially in time for Spring) when pond fish diseases get out of hand.
Youtube for Fish Medicines, Diseases Symptoms and Cure
Also, don't forget about the book, Dr Erik Johnson's Koi Health and Disease 2
Finally, if you have not seen the section in Koivet about "twenty steps to pond fish health" it's a section of Koivet that takes you "step by step" through an orderly process to lead you to a clear picture of why your fish or pond is "sick" and it starts with water quality. (Video version)
I've uploaded a video that's a favorite of mine, lately. It's about Adding Beneficial Bacteria to Aquariums to speed the cycle. It's an established nitrification system with no break in, over night.
In case you missed it, I've got a growing Youtube channel with all my fish health videos and it's growing all the time. Doc Johnson's Youtube Channel for Koivet.com
Also, Koivet.com is being overhauled to a WordPress theme to be the best fish health, fish medicines symptoms and cure web site out there. Videos and pages melding into a comprehensive "course" to bring you up to speed with "what you should know" videos and pages.
Finally, I have my book on amazon.com which means if you have prime you can get Koi Health & Disease 2 overnighted in the event of an emergency.
So, I've got all my domains (almost all of them) on WordPress and so I have a lot of work to do getting them set up for articles and such!
Hopefully I can get things "informative" quickly. In particular I want to get Watergardeners moving as quickly as possible!
In the meantime, check out my Youtube channel?
