Most folks will tell you that the Top Fin product does not work. This type of (wrong) Nitrifying bacteria is not one that is self sustaining and you will need to continually use it or add a source of ammonia to your tank,either with pure ammonia, fish food or a piece of raw fish such as shrimp that will break down and start producing ammonia which in turn will start your cycle.Also, it has been reported that using the Top Fin will cause a cloudy water, and some claim that it is the bacteria 'bloom' starting. Without a source of ammonia, that bloom will die off rapidly.
There is pretty much only one type of beneficial bacteria in a bottle that works on the market and that is the Tetra Safe Start.
Also in order to know where you are in the cycle you will need to get yourself a NitrAte kit. Once you start showing some ammonia on your
test kit, I would then proceed to start testing your nitrIte soon after. Once you start seeing NitrIte showing up, I would begin testing the NitrAte.
I do not believe your tank is cycled and I believe there is no source of ammonia in your tank for the beneficial bacteria to really take hold of and grow. I would suggest the raw fish method, It worked great for me.
