new tank disaster

[Paul.r.g]

Set up new tank, flowed all the instuctions and advice given.
set the tank up, and fully running for a week, using all the chemicals (and cycle bug culture).
added 3 fish (zebra daneos) as recomended by the fish shop

5 days later noticed v.small white patches on one of the fish, diagnosed as fungus.
Added the antifungual compound from the fish shop, but all fish died

I need to know my next course of action. (the water now tests perfect).

should I let the tank filter out the chemicals using a carbon filter, or start from scratch, keeping the filter as is, or clean every thing compleatly.

Help

I'm sorry to hear about your loss.

Is the tank still cycling?
What is the ammonia, nitrate, nitrite and pH?

 

[Paul.r.g]

thanks for the reply
to anser your questions

I don't know if the tank is still cycling, had an algae bloom but the tank has cleared it's self (some small particals still floating round in the water but getting less)

got some "tetratest strips" to test the water, doesn't show ammonia, but the
nitrate (NO3) has droped from over 100mg/l to between the 0 - 10 mark
nitrite (NO2) has droped from over 10mg/l to 0 -1 mark
PH is between 7.2-7.6
also water hardness (GH) is showing at less than 3 deg ( what ever that means)

Is that all the info you need.
I was worried about the funges spors in the tank, do I ?

Hi Paul,

Ammonia is very harmful to fish, so you should test it before you add anymore fish into the tank.

How long has the tank been set up?
Are there any fish in the tank now?

 

[Paul.r.g]

Had the tank set up for 3 weeks now.

after all the fish died, have done a 75% water chamge

left the tank for 5 days then took a sample of water to the fish store where they tested the water, all checked out fine.

now have 6 small teteras in now

hope thease do better

HiYa and welcome paul

It sounds like it may have just cycled - keep checking the water and feed sparingly

I'd leave it anotheer couple of weeks before adding any more to be on the safe side


good luck with them

Hi Paul.r.g

It sounds to me like you got some bad advice from your lfs (local fish store). This is not unusual and many of our members joined to find the answers to similar problems.

For starters, I suggest you read this thread so that you will understand what your chemical readings mean and why they are important:

http/www.fishforums.net/index.php?showtopic=10099

Since your chemicals test OK, your tank is probably cycled and by adding fish slowly, the beneficial bacteria will have a chance to reproduce enough to accommodate them too.

About the fungus............ Your fish probably had a low resistance due to stress during shipping, change in water, etc. Or, if it was truly fungus, he might have had a small injury that you did not notice. Since he is gone now, and you have done water changes, you have nothing to worry about.

There are good and bad bacteria living in your tank. The idea is to cultivate the beneficial ones and keep the number of the bad ones at a minimum. Regular water changes and bottom cleanings will do more to promote healthy conditions for your fish than anything else.

As for the pH and hardness tests, you will not have to pay much attention to them at all unless you are at a stage in the hobby where you want unusual or especially delicate fish, or if there is something about your local water that causes extremes of these readings. Usually you are best off to leave them alone.

Good luck with your aquarium. I'll be looking forward to reading your posts.
