Need Help! Very High Ammonia!

Will you answer the following so we can help you?

What water conditioner are you using?

Would you post your tap parameters for ammonia, nitrites and nitrates? you mentioned your tap ph is 6.4.

Re-check ph in your tank today, what is it at?

How many fish are you left with? remind me the size of tank please.

How much water do you normally change out and how often?

What were their symptoms before death? Will you describe?

 

Sad to hear the loss, the ammonia built up is so toxic , its really makes fish so weak , I also faced similar problems, I would suggest, a large water change and add prime + seachem stability as per directions, also to not feed for a few days to keep post feeding ammonia spikes low ...

What filter you are using, I would suggest using sponge filters, very cheap but really effective for Beneficial bacteria growth , if you have canister filter, try about 100 ml of seachem matrix , it really works wonders ..
