Hi Guys
Please help with advice...my fish are dying left right and centre.
On the smaller fish it looks like they have a "ballast" problem...spiraling to the bottom..lost 4 very small ones to date
Today i noticed that a bigger fish is showing the same symptoms ...and it looks as if the fish are experiencing a muscle spasm...

Im draining 1/2 my pond to refill with fresh water and salt..any other advice would really be appreciated

Hi

1. Where are you located?
2. What is your water temperature?
3. What is the water Total Alkalinity?
4. How many koi in the pond?
5. How big is your pond?
6. How long have you had the koi?
7. Have you added any new koi lately?
8. Have you done any water treatments lately?
9. How often do you do water changes?
10. Do you have a filter and pump that runs 24/7 on the pond?

Lots of questions but this should help us figure this out.

I hope the info is usefull Wayne
2 of the big fish were emitting a white foam like liquid from their sides ...???

Hmmm, white foam...that does not sound healthy.

How is the 6 new babies doing?

If i had to guess i would say your new babies introduced something bad into your pond.

Go to the members section and contact Chris Neaves. He is a member on this forum and he is the health expert of SAKKS plus he lives up their in gautengeleng. I think you need someone with knowledge to come and give you a visit.

Thanks Wayne will do

I hope I read point number 9 wrong! Why only changing water every 6 months?

Martin.

Jy is "overstock" (5000lt @ 12 Koim= 416lt per Koi)

Hou dadelik op voer en doen 20% "water changes" elke dag vir ongeveer 5 dae.
Kry dan 'n toets stel en toets die amonia en nitrite in die water.
Kyk of jou vis "flash" ( hulle krap hulle self teen die onderkant en kante van die dam)
Is daar enige rooi merke of sere op van die Koi, hang hulle in die water of swem hulle normal.

Jy kan vir Colin Nel (083 451 3284) of sy vrou Lee-ann (083 387 3177) kontak, hulle is in Pretoria

Dankie Pieter, ek het nie geweet of jy nog op die forum is nie...dinge is maar stil hier deesdae. Jy sal die mense en hulle ligings in daai area baie beter ken as ek.

My gut feeling is that martin is experiencing a PH crash but the fact that the new koi are ok and the older once has died does raise other concerns...but lets rather get some other experienced hobbists on site to investigate.

Baie dankie Manne vir julle bereidwilligheid om te help.
Ek gaan vanoggend nog vir Colin of Leann n luitjie gee.
Sal julle op hoogte hou van wat aangaan

Groete
Martin
