Yes, you have to protect your filter nitrifying bacteria from clorinated tap water but if the filter cartridge is beyond repair throw it. However have some of protection over the nitrifying bacteria in the filter protected. Try adding Cycle or other nitrifying bacteria brands to the tank water. Remember protect the nitrifying bacteria at all cost if the nitrifying bacteria dies your fish start to die.

Good luck from Josh.

I agree with almost everything Josh said, except for adding cycle. IME, it just doesn't do a thing.

As far as your filter goes, regularly changing it is probably the source of the ammonia/nitrite issue. Rather than changing your filter media, rinse it in the tank water you remove when you do water changes (it is already dechlorinated).

Each time you change your filter media, you take away the majority of the bacteria which consume ammonia and nitrite. So, if you are always changing your filter media, you never have enough nitrifying bacteria to consume the ammonia and nitrite. This is almost assuredly the cause of the prolonged nitrite and ammonia.

On an aside, but to demostrate, I have been using the same filter media on my 29g for almost two years. I simply rinse it every other week as I do water changes. I haven't had a single detectable spike in either my ammonia or nitrite as a result of rinsing.

If you take this approach in conjuction with the advice Huntress gave about using Amquel, your nitrite and ammonia issues should resolveed within a few weeks.

Hope that helps.

Well, I tested my water today and the Ammonia was in between 0-.25, nitrites 1.5, and nitrates at 5. Does anyone have any suggestions of what to do. I had another Zebra Danios die this morning. It was at the surface breathing really quickly, had white lines across his back, his gills were swollen but not that red, and his stomach was swollen and it looked like he was bleeding from the inside.
Thanks for the help.

Well, I bought a bottle of Amquel+ and put the amount specifed on the bottle in. I tested the water the following day, and the Nitrates were at 5, Ammonia at 0, and Nitrites at 0.25. I waited the specified time and added another dosage, but the Nitrites stayed the same. The bottle says it removes more than 2 ppm of Nitrite, but after 4 doses it stays at .25ppm. If anyone has anymore suggestions, I am really getting stressed out because it won't go down.
Thanks for the help.

Have you done any water changes in conjunction with those 4 doses?

Yes. I do do a 20% water change every three days.
