Hello, I am a newbie and just set up my first tank it is a Fluval 13.5 nano. I put turbo start and ammonia to start, added a little extra bacteria, I have a ton of matrix bio rocks in the filter and a good 1.5” of sand. My ammonia is just not dropping and it has been about 4 days now and I am starting to get worried. I have tested each parameter and I’m not sure exactly what they are (I’m a bad color guesser) and need help knowing if my tank is cycling or should I start over?
