Hello, I started the fishless cycle on my 20 long the friday before last, however I had to switch the filter for a better one last friday so I'm going to assume that at that point I started over. When I first started, I dosed my tank with that special ammonia to get it to 4 ppm, however I'm not sure if I overdid it. I'm having trouble matching the color on the water test. I was wondering if someone might be able to tell me what this ppm reading says? Thanks. I apologize for posting so much, I've just been needing a lot of help.
