Biozyme work for my 30 gallon fish tank?

So, it is my 4th day of cycling a fish tank doing the fishless method. I put pure ammonia in there (I'm sure I used the right kind of pure ammonia with no substrates, dyes, and perfume, etc) and so far it has only been cloudy. I heard that the cloudiness is a sign of a bacteria bloom, but I really want this to hurry up. I know I need to be patient, but I heard that Biozyme will fasten the cycle. Is that true? Will it still work if I already put in pure ammonia? The ammonia level now is high, and I have no nitrites nor nitrates. From personal experience, how did putting the biozyme in ur tank work out? and how long did it take for u fish tnak to be fully cycled? Also is it safe to put Biozyme when I put pure ammonia a few days ago?
