Question: Fishless cycle using API quick start and Dr. Tim's ammonia

[matthewg]

Hey everyone, I have a 20 gal tank and trying to begin the cycle. I've added Dr. Tims ammonia and the level is currently at around 4ppm then added api quick start to the tank but no signs of nitrites yet. it's been a couple days and i'm not sure if I should add more quick start to the tank or just wait. What should I do?
