two pumps (one is a new fountain pump (Beckett) and the other is the

The pumps are on GFI circuits so I don't think there could be a large
short circuit. There are Lava type rocks in the pond which, once
again were in there with the koi for over a year without problem. I
did power wash the rocks prior to putting them back in the pond. The
water temp is in the low 80's. The water is perfectly clear. Please
any help appreciated since I am at a loss what to do next.

Did your powerwasher ever hold soap or other cleaning supplies?
With repeated losses in such a short time, there is something toxic still in
the pond. Garden fertilizer? Decomposing residues fro before? I don't
think a high turnover with chlorinated water would have killed the first
batch. Were there any other changes in equipment at that time?

Jim



The powerwasher has never had any kind of detergent or cleaner used in
it. My wife said she had added plant fertilizer to the plants, but
she said she had used this before without problem to the koi. In
addition my last two unsuccessful attempts to add fish were done after
multiple water changes with all plants/fertilizer removed. Following
the death of the first fish, the pond was totally cleaned with very
little residue left, with the exception of some crevices from the lava
rock. If rotting residue were the problem though, wouldnt there be an
ammonia spike? What I am planning to do is to remove all material
from the pond (pumps, rocks, everything, add water only and
conditioner) to eliminate all variables.

Are you using the same equipment to refill the pond each time? Could there
be some kind of contaminate in the equipment to refill the pond? I wondered
because you probably used a different system to fill the bowl. Just a
thought from a new pond person. Kc

How is your water treated, by whom? Some municipalities have stopped
using chlorine to treat domestic water and have started using things like
ozone, bromine partly to improve the taste and partly because they have
longer half lives and are considered more effective. Check with your
water supplier.

How are you refilling the pond? If you are using the automatic re-filler
mentioned above try filling from some other source. Use the kitchen tap
and a hose. I only suggest this as your problems started when you turned
the automatic system back on.

If the water is still being chlorinated the a test for this might be to
fill a small container with tap water, either let it sit for 24Hrs or add
de-chlorinator and introduce a small fish. If the fish survives try the
same thing using the water source you are using to fill the pond. Take
the sample at the point it enters the pond, but don't take it from the
pond. If the fish survives this part of the test then the problem is in
the pond, if it doesn't then the problem is in the water used to fill the
pond.

WARNING, If the fish doesn't survive part one of the test GET YOUR WATER
TESTED YOU MAY BE AT RISK!

What's the fish look like when it dies? Does it have all it's fins or have
they been eaten away leaving only the thicker parts? Are there any red marks
on it's belly? Do the gills look normal or are they red? Two things that can
kill are different water temperatures and different PH. Chlorine (or other
chemicals) normally cause red gills. Nitrites usually cause red belly. Fins
eaten away is usually PH.

Timothy, did you use any solution (detergent, etc.) when you power-washed
the rocks?

Is it your power washer, or did you rent it? If you rented it, there might
have been sufficient chemical in the power washer for the rocks to absorb
t -- especially at the pressure generated by a power washer. I think many
power washers are rented by people who use them to apply Clorox to house
siding or deck before painting, or to remove mildew.

Also, what did you use to clean out the sludge on the bottom? It seems
unlikely that any contaminant would be introduced using a shop vac to remove
sludge, but I suppose it's possible.

Default Fish pond water kills all fish within 24 hours.

I've been thinking on this one all day. It appears as if all the variables
are covered. My one suggestion for cleaning the lava rock is to put it on a
grill and cook it like a steak: it will burn out any residue that's in the
rocks, and nothing is left after they heat up. It doesn't smell too good,
but it's an extremely effective way to clean the rock, much more effective
than simply blasting it with a hose or power washer. If the pumps were
leaking, you'd notice the film on the water. After the water's been changed
so many times, one would "assume" that anything toxic had been washed out.
To ensure, I'd nuke the pond with a heavy PP dose which would neutralize
most toxins, then maybe put a couple of pounds of activated charcoal in a
knee-high stocking for a few days where there's heavy water flow. Between
the two, if there are any toxins in the water or on the liner, they will be
removed. Because the fish lived in the same water in the house, but died
when placed in the pond, it leads me to believe some of the simple things
like pH differences, water temp change, fish stress in the bag (ammonia?
heat from the sun?) The power washer is suspect, but if you say it hasn't
been used for anything toxic (BTW, fertilizers CAN be toxic . . .) then the
above recommended things would cure that, especially firing up the lava
rock! This is a tough one: everything I can think of has already been tried
or eliminated. I'll keep thinking, and maybe someone will trip over the
answer.

Best of luck,
Lee

Default Fish pond water kills all fish within 24 hours.

Thank you all for your thoughts. The pond has always been refilled
using an auto-refill valve put in by the original landscaper who
installed the pond. The fact that fish lived in a bowl of the same
treated tap-water that is used to fill the pond suggests to me that
the problem does not lie in the municipal water source. It is
possible that it has something to do with the auto-refill I suppose.
As far as the pond liner, it is one of the preformed liners from home
depot, so I doubt that that could be the problem. As far as the
pumps, there is a waterfall pump (Beckett waterfall pump) and a
Beckett medium fountain pump. As far as the water parameters,
recently the temp has been around 83 degrees. The pH measured at
about 8.0. As I previously mentioned the ammonia level was tested by
the LFS, who reported that is was a little high (I am afraid I dont
remember the number or the units) but not deadly. The fact that this
pond and all equipment, and rocks in it supported fish successfully
for the past two years, is what is so confusing and frustrating for
me. I will try to test for some of the other parameter mentioned.

A couple of questions.

I read that you have put goldfish in your preform that you had in a
bowl with the same declorinator/ conditioning solution that you use in
your preform. Did you get your water from the same source? That is,
when you fill your preform, I am assuming that you fill it with a hose
or its dedicated water source. Is this correct? I have seen garden
hoses break down chemically over time and become toxic.
The same with underground sprinkler systems.
Let get rid of that variable also. Try to use the same source of water
that you used for the goldfish that you had in the bowl.

Default Fish pond water kills all fish within 24 hours.

To address the power-washer concerns, the washer has been used by me
only. It has only had water used in it. Nothing else, nada, no
detergents, no fertilizer, nothing except water from a hose receiving
the same municipal water. As far as what the fish look like when I
put them in. This does cause me some concern. When I first put the
fish in, it appears as if something really irritates them. Most of
the fish I have witnessed appear to intermittently dart around for
about 2-3 min, and then appear to settle to the bottom in a upright
(i.e. apparently resting) position. One of the goldfish that was
first added, I found had actually jumped out of the pond. I put it
back in, and it died within 10 mins. I have then witnessed several
fish die within 10-20 min. I think this makes it clear that there is
no other creature/critter involved in killing them. It further seems
to support some toxin/strong irritant killing them. Upon dying, I
have really not noticed any redness anywhere on the fish. They simply
look completely normal except they are limp and dead.
