I'm not sure what im doing wrong, i am doing a fish in cycle on a 20 gallon and i've been using stability and rime for over 2 weeks and still no nitrite... I use one capful of stability nightly and pour straight into the filter. I dose prime nightly as well and if ammonia goes up i do 20-25% water changes. My ammonia reading Saturday was 2.0 so i did a 20% water change and tested again yesterday and it looked closer to 1.0 but still no nitrites am i doing something wrong? Should i quit with stability and wait to switch over to quick start?
