My tank has been cycling for a little over 4 weeks now. This time last week my ammonia finally disappeared with nitrites at over 5ppm and nitrates hovering around 20ppm. I dosed the tank up to 1ppm ammonia to see how fast it would process it and it went away after around 36 hours. That was Thursday so I dosed it to 1ppm again and it only took around 24 hours this time. Nitrites still unmeasurable with the kit. I tested again today and nitrites are still over 5ppm(API test kit. It turns dark purple right away) but my nitrates are gone. I tested it again just to make sure I didn't screw anything up and got the same result. I've never had this happen before. Any ideas as to what might be going on? I'm thinking either my nitrite or nitrate test kit is bad.
It's a 10g tank setup with all BRS reefs aver dry rock and dry sand.
