Just done a check on my water stats,the results are as follows.

Ammonia 0.25.. this is coming down by the way.
Nitrates 0.ppm
Nitrites 0.25 ...this has gone up over night and has been stable for 5 days,with a reading of 0.ppm

My PH has also dropped overnight it is now reading 6.8 and has been around 7.2.

Why have my Nitrites and PH changed so much overnight?
It has been up and running for 4wks now.

I'm beginning to think that my tank hates me.

Your comments would be gratefully appreciated.

Thanks.
 
Can you give us the same readings on your tap water? Let the water sit out overnight in a shallow dish for the pH test.

What size tank?
What kind and how many fish?
Size of tank and filtration?

How did you originally cycle the tank?
Test strips or liquid test kit?
 
Hi rbishop thanks for your reply.

Just done a test on my tap water and the readings are........

PH 7.6
Ammonia 0.ppm
Nitrites 0.ppm
Nitrates 0.ppm
This water has been stood for 24 hrs by the way.

My tank is a Jewel Vision 180 bow front.
Filters include a internal filter that is built into the tank ,and we have added a Fluval 250 external filter.

Currently housing

2 platies
2 silver mollies
4 cory's
2 guppies
1 blue ram
6 zebra danios.
2 small clown loach which will later today be removed to a bigger tank.

My test kit is a liquid one and i did a fish cycle.

Hope this helps.
 
My tank has been running for 4 weeks now.
And i started with 6 Zebra danios and 2 platys.
 
If your tank has only been up and running for four weeks it is entirely possible thst your tank has not finished cycling. I also think that this is a lot of fish for a tank that has only been up that long. You need to slow down. Your tank and everything in it will thank you.

When doing a fishy cycle, as I assume you did, it takes a long period. Your best bet would've been just to let the original danios and platies swim around for 4 weeks, before adding small groups on a fortnightly basis. During this process you should monitor all water parameters and respond accordingly with water changes to any elevated levels.

Your tank hasn't had a chance to complete a cycle yet, so adding new fish just upsets the balance and sends it into another mini-cycle. This is where I think you are now. The new fish added too much ammonia for the subsequent bacteria to convert to less deadly forms (Ammonia > Nitrite > Nitrate). Think of it as if your tank has to go through a peak in each, and then it will be cycled.

So,
Ammonia is dropping (the 1st peak, and most deadly)
Nitrites rising (the 2nd peak, not too fish friendly)
Nitrates zero (the last peak, but should be in the region of 10-40ppm in a cycled tank)

By this logic, you're about half-way through the cycling process.

You may want to do a water change if the nitrite level gets too high, to protect your fish, as these can damage their physiology (am very tired and can't remember what!)
 
pug,
it affects the gills of the fish(the biggie) and can affect O2 uptake and absorbtion.

I would recommend water changes to try and keep ammonia and nitrites at .25.
 
Yep, sounds alot like you added to much fish first. With a new tank, what you want to do is add fish in slowly.

Or, go out and get BIO-SPIRA.
