That would be your problem. No ammonia source means no cycle. The bacteria stuff you added was most likely just your typical bacteria in a bottle supplement. Some say the stuff works, others will tell you it's junk. Fact is, it's not doing you any good without and ammonia source anyway. Go grab a few raw, unseasoned shrimp from your grocery store and stick them in a sealable sandwich bag. Poke some holes, about the size of a pencil in the bag. Place the bag in the tank. Over the course of a few days to a week, the shrimp will decompose releasing ammonia, which then will start your cycle. This is the easy way. Depending on the size of tank, you may be able to just add a pair of clowns as long as you watch the parameters closely and are prepared to do a water change. What size tank do you have?
