If this is a new tank then just chill,,,are you using an overside filter, if so beg borrow or steal a used filter pad and add it to your filter then wait a couple of days. Then add a molly szed hardy fish about every other day until you are at the bioload you desire, then replace the cheapies with the fish you want to keep. Stop trying to hurry things with additives. From the time I first add water to a new tank it takes me around a month to start adding the "keepers". 3 days with just water and a running filter, another week with plants and a little fish food, another week with a few cheap tetras, guppies, mollies, glass shrimp, etc. And another week to add enough cheap fish and a couple corys or plecos to bring the bioload up. Then I start replacing the cheapies with keepers.
