I'm currently cycling my first ever tank, so I am very new to this and didn't even know about the nitrogen cycle before I started this. I'm doing a fishless cycle and my tank has been cycling for a few weeks now. My problem is that I have high levels of nitrates (about 120ppm) but also very high levels of nitrites (my test goes up to 10ppm but the color seems much deeper than anything on the test so I assume it's even higher). The nitrates are steady at 120ppm but the nitrites aren't decreasing at all, and it's been this way for almost a week. I did about a 15% water change a few days ago but that didn't do anything. I know my test isn't faulty because I've tried different ones and got the same readings each time. I really wanna add fish as soon as possible but I just don't understand why my nitrites aren't going down!! Also I've been adding a half dose of ammonia every other day bc I'm afraid of the bacteria starving and accidentally breaking the cycle. Any help would be greatly appreciated!!
