I did not want to open a thread for this but now I am really wondering what is going on.
I have followed the fishless cycle on this website and was able to speed up the process via a filter a friend of mine let me borrowed from is 55G tanks (I have a 20G tank btw).
So, at the end of cycling, I was adding 4ppm of pure ammonia in the morning (around 8am) and 4ppm the same day around (11pm) because it was completely gone by the time I added it for the second time.
Anyway, that is not the problem. I went through the NitrItes pike not too long ago and on Friday, I finially see the NitrIte going down. I continued adding ammonia and now, after 24h I can see that all of the ammonia and NitrItes disappeared which is great...
...BUT, my NitrAtes are really high. I know that it is normal to see High NitrAtes but I did a 90%pwc
this morning and after I still had high NitrAtes. I did a 50% pwc
tonight and vaccum my gravel and I still have a good 30ppm of NitrAtes. So I am king of confused since I have not added ammonia since yesterday and I have no NitrItes anymore.
Is there a reason why my NitrAtes are that high? Can it be because of the Filter my Friend let me borrowed from his tank?
Please let me know since I can't wait getting my new fish very soon.
Thank you in advance,
