I have a 3.7 gal saltwater tank. I used Imaginarium Pacific Ocean Water bought from the local pet store, I added live rock/sand, biological booster, and ammonia for a fishless cycle. Ammonia and Nitrates have remained at 2ppm and Nitrites 0ppm for 3days straight. I've been told my tank must not be cycling, hoping someone can confirm or tell me what i did wrong?
