water change tank wipe out

well did a water change on Saturday and i started
to lose fish so we tested the water the readings
are a read

ammonia 0
nitrite 0
nitrate 15 ppm
pH 7.6

so we run the tap for 30 minutes
dechlorinated as always and changed 25%
again only to find that they were still dieing
anyway i am down to one B/N now which
seems to be OK so far touch wood i have just
tested my tank again today to find
the readings are just the same well it just goes to show
that it doesnt matter how many years of fishkeeping
you have under your belt it all depends what comes
out of the tap so here we go again start all over again
and no more water changes over the week end

It was quite upsetting to lose fish over a period of 24 - 48hrs.

Id be a little annoyed and probably give up.

Unfortunate. Yep It can happen to anyone and always does when your least expecting it lol.

this sucks i had same onces with losing loads of corys, i'll sort u out with some bn's tho no problem at all

cheers carl

I know your pain mate, its soul destroying

sure is a illegitimate

I was on the verge of giving up, but someone said to me pick yourself up, dust yourself off and start again. So i bought some more fish which seem happy in the tank.
But unfortunetly i lost the last bristlenose. It must of been weakened and didn't recover. So i'm on the lookout for some more bristlesnoses.
I wont be doing water changes on a weekend from now on, lesson learnt.

Kev has more bristlenoses again so does Cleveland think his are albinos look in the for sale thread mate

Whats with changing water on a weekend? Why does it make a difference?

You can sometimes get chemicals etc that have ran into our tap water from time to time which can kill our fish. And as you can see does not affect our water tests. Unfortunatley peoples fish have died through this, you could use rain water to avoid this.

its all depends when the dose at the water works
as it will be stronger the days after also if they have
been doing mains works they dose with chlorine or chloramine
or a disinfectant and that can kill fish

Believe me Texpis like MarcG and The Biffster said it does make a difference. People take tap water for granted. It gets treated at the treatment works before we drink it.
We haven't done it for a while but we used to get a readout ever so often of the content and quality of the water from Northumbrian Water and you will be surprised at what it contains.

Yes I can well believe the chemicals etc they put in tap water. What threw me is changing water on a weekend I don't see where the weekend comes into it. I have 2 water buts in the back garden collecting water from a conservatory am I better using this water? I was worried it might have parasites etc in it!

Mick

Boil it. Kill the parasites if any then dechlorinate once cooled. I would think that would work. If you can afford to loose a fish put one in a seperate tank with the water( I wouldnt use a hardy fish). Either way it should save you money if your going to try it because if you used this water and it killed all your fish youve lost money. If it works you can use this and avoid deaths from tap water.

And for the weekend thing am guessing was coincidence and the biff is waiting for the water to return to normal

the only thing i worry about with rain water
is were and how it is collected and whether
there is any factories near by which venting
off in to the atmosphere of near a road
all this has to be taken in to account i used to
use rain water the only thing you need to do
to use it filter it through activated charcoal filter
and bring up to tank temperature the filtering should remove most things from rain water i am looking
at hma filters again now

starting to restock now
2 pearl gouramis
6 pygmy Cory's
4 bristle nose cat fish
2 hoplosternum thoracatum

Good hopefully some better luck this time.

strange one water change it started with
24 to 36 hours later the whole lot gone
people changing water be careful run the
tap longer use a the correct amount of
dechlorinator or hold the water change over
for a few more days just to be on the safe side

i've just added an extra (air fed foam) filter to the tank with the youngsters in so in effect it should mean less water changes ergo less risk mate besides as i keep varying between bloodworm, liquifry and dried brineshrimp the extra filtration will do no harm i don't reckon like

no it should be OK that Ian always
better to have a bit of extra filtration
where fry are i think as they don't always eat
everything and the water can always get a bit
foul rather quick
