The bacteria that will eventually become your Bio-Filter are not free swimming and have nothing to do with the cloudy water. Nor will the white cloud attach itself to something and “go away”.
Usually there are two primary reasons for “white water” in a new tank. The first would be dust and dirt particles so fine that your filter will not filter them out and they keep circulating and reflecting light, that is why they are white. They will eventually precipitate out and be vacuumed out or filter out when they start to naturally stick together and become larger particles. The second is a bloom of bio organisms “loosely translated as bacteria” which can show up anytime really, but will disappear when whatever is providing the fuel is consumed. Neither of these “white clouds" are harmful to your tank, just annoying until they go away.
The chemical you are using is designed to make the particles stick together, become larger, and thereby help the filter with larger clumps. The problem here is that these agents are short acting and break down releasing the small particles back into the water column.
Patience or a Diatom Filter are the solution.
