This was all done in one day and ever since then I have had this white cloud.
You replaced all of the filter sponges in your filter? The beneficial bacteria takes home in those filters, so if you remove them, it would cause another cycle I believe. When I had a white cloudiness to my tank, it was the bacterial bloom establishing the cycle. If your filter has two sponges, I would replace one only and leave the other one. But even at that point, it would only be necessary if the filter sponge is extremely clogged with detritus that replacing it would be required. Most of the time, just a squeeze and a rinse in tank water or water that has been dechlorinated would suffice.
