KOI DEATHS - Please I'am losing my best Koi tonight

Post by Mark Slat » Sat, 07 Jun 1997 04:00:00



My Koi are dying :-

Two weeks ago there was a bout of fungus - This was treated with a
fungus/blanket weed cure (can't remember the name). The problem was
still apperent so after a 30% water change the treatment was repeated.

The fungus has now gone but some Koi are laying on the bottom
motionless - They react if a net appears close and bolt round the
pond.

Problem is they are dying and I can;t explain it !

Water tests are good accros ammonia nitrite nitrate etc but
I did add 100KG of sand to the filer about 10 days ago - the sand
was advertised as sterile for use in a childs sandpit

The UV is running and the water clear

Help my favourite one looks next - performing water change tonight !

Hi Mark,
Living in the UK you have the ultimate in Koi health at your fingertips.
Have you attempted to contact Peter Waddington at Infiltration or Bernice
Brewster?  How about the group that publishes KOI Health Qtrly.  In the US
you can contact Dr Eric Johnson thru the AKCA website.  Good Luck!
Best regards,
Nancy Ash

I think you're changing too many things too quickly.  Since the water
tested OK, leave everything alone.

IMHO, stress is a large part of the problem (to both you and the fish!)

Whatever is done is done and doing another water change will only make
things worse.  You seem to be implying the sand might somehow be
chemically treated - I have no idea about that but I think you need to
let everything settle for a few weeks.

I am assuming of course you used de-chlor and de-chlormine when you
did your water change.  If not, that could explain it.

Good luck,

Kurt
