Using natural seawater for disease treatement.

[JasPR]

I guess that would all depend on what micron filter size you use? Or maybe a rapid sand filter and a micron screen system?
A UV system alone would be no good as the live and also dead results would still decay. JR

Small world Mitch. We have since come out with a banggai cardinal production manual. It can be found here...

Thanks for catching and correcting that. (too long away from the lab ) I'd hate for bad math on my part to potentially lead someone to a mistake

I received a copy of Koi Kichi by Peter Waddington for Christmas. I was reading the book with great interest when I notice a bit about a koi farmer in the Niigata area carrying seawater up the hill to treat his young koi for Spring virus disease. Waddy says the koi got better and there were no negative effects from using the seawater. Must have been a heck of a job if the pond was very large.

Hi Mitch,

Did he mention how the breeder treated the Koi? Was the salt water diluted?

Russ,
This comes from page 195 of Koi Kichi by Peter Waddington.. It is under the title of "The Art of Breeding Nishikigoi In Japan" He is talking about fry born in the Spring and dying of "sleeping sickness" at the 3" to 4" size. Anyway read it for yourself. I'm sure it was full strength seawater used to get the pond to 0.5ppm.
Mitch

PS
I hope JR sees this.

Hi Mitch,
My understanding of the passage is that the sea water is dumped into the mud pond to get a level of 0.5ppm. This is diluting the sea water. I seem to remember that sea water is 27% salt. Correct me if I am wrong.

Full strength seawater is 3.5% or 35 parts per thousand. A 10:1 dilution to get 0.35%. That's about 100,000 to 200,000 gallons of seawater for a 1-acre pond. A large tanker truck can carry 40 tons so you would need about 15 larger tanker trucks for a 1-acre pond. Not something you would do with a bucket.

Can you humor a novice and explain under what conditions you might consider raising the salinity of a 20,000 gallon system to 0.30%?

Also, nitpicking on the math, the calculations assume that the pond is starting with a salinity level of 0.00%. Most source water has between 0.02-0.05%.

To filter seawater, I suspect you would be best off using a series of filters, starting with a fairly coarse particle filter. We camp on land that has a well for potable water, but straight from the tap it is nasty. If you run it through a particle filter, RV (recreational vehicle) cartridge filter and then a separate AC cartridge, the grit, odor and much of the iron is removed. Without the prefilter, the other filters don't last more than a day.

Are you talking about tap water as the source water? The source water here is mountain water, which I would assume is 0.00%.
