Hi all,
I have a mature pond about 8 years old, 800 gallons, about 50 goldfish
ranging from tiny tiddlers to about 5" long, plus one really big ghost koi
about 18" long. I have all the usual filtration, waterfall and oxygenating
plants, UV light, water is nice and clean and clear and always has been. I
feed the fish about every couple of days - if they get too much they get
frisky

Just what the hell is a dam "Tiddler"
Clean clean water does not dictate water quality by any means..
Care to expalin what "usual" filtraton is........

Big problem - In the last week I've found 3 of the larger goldfish just
floating dead in the water. They have no signs of any disease and look
perfectly OK, just dead.
So looking perfectly OK...dead is normal for you?

This is very distressing as I'm spending every
moment checking the pond and expecting all my little friends to die.
By checking the pind are you putting your eyeballs on the fish to see
if any more die or are you doing wtaer parameters and making
ajustments. Checking the pond is a word that is useless useless unless
you state WHAT your doing.....
I put
some medifin in the pond a couple of days ago (I treat it twice a year
normally - Spring and Autumn), but I've had another death since then.


So are you know to arbitrarily shot gun treat fish just so you can say
you did somehtiung rather than finding out what specifically is wrong
and adjust accordingly? Sounds that way. Why add a med type supplement
when perhaps all they mneed is better water conditions Get a test
kit and use it.

The only thing that's changed recently (don't know if it could possibly be
the reason) - I recently netted the pond because we were visited by a heron,
then I realised that the frogs and newts couldn't get in and out so I put a
length of wood into the water from the side. the wood is sapele (sp?) and
is definitely untreated, but I know some hardwoods have funny substances in
them - do you think this might have poisoned the water ?? What shall I do ?
Please get back to me soon - I'm desperate to save them


I doubt the heron or the newt has a thing to do with the problem, nr
the wood, but it would propbably be prudent in your case to remove
wood............but applicable test kits and post results. Other than
that yu may as well continue using your medfin since its only a shot
in the dark and continue your quest to watch the pond instead of
correct what more thanlikely is a water parameter (quality)
problem.....
Thanks, Carole
