I'm trying to cycle a hospital tank so I can treat my fish for white spot.
It's a 55l tank with a allpondsolutions Fish Tank Filter, 450IF.
I removed the active carbon and replaced it with some bio media from the sump in my main tank.
I started the cycle last month with some Dr Tims one and only along with Dr Tims ammonium Chloride.
I added 55 drops and ammonia went off the scale, but about 1 weeks later I saw a drop and a rise in nitrite and nitrate.
But since then nitrite has been off the scale.
It's been 3 weeks now and nitrite has not dropped. A week ago, I did a 50% water change, but today, test results are still max.
I'm using a red sea test which says to wait 9 minutes. But it turns deep red within 30 seconds.
What am I doing wrong?
