When I first started out with FW tanks years ago, it was recommended to me that I use Cycle to speed up the cycling time of a new tank. So I bought some, put it in my tank, expecting the tank to cycle more quickly that the usual 6 weeks I'd read it usually took a new tank to cycle. Well, even after using Cycle, the tank still took 6 weeks to cycle
I concluded that Cycle was a useless product and have never wasted my money on it again.
From your post, I'm guessing that you want to add "nitrifying bacteria" that will eat up or neutralize ammonia and nitrite. For that purpose, Prime or Amquel will neutralize toxic ammonia to non-toxic ammonium. Prime also says on their bottle that if you add extra Prime, that it will also "remove" nitrite and nitrate. I tested this claim a while back, and extra Prime does do something to nitrite and nitrate, but for the life of me, I'm sure it does not "remove" but converts these substances into some other form of nitrogen.
Get hold of some macroalgae and toss it into your tank. It will slurp up ammonia, nitrite, nitrate and phosphate. The more macroalgae you have the better it will work, providing you have light over the tank.
BTW, what are your ammonia and nitrite levels?
