It sounds like you did a fishless cycle, but how did you cycle the tank without a test kit? How much ammonia were you adding? What were the ammonia, nitrite, and nitrate levels when you were done cycling? When I was an ignorant newbie, I thought that "cycling" meant turning on the filter. I almost killed my fish when I put them in a new tank with the water "cycling" through the filter. The water turned very cloudy, and the whole house had a bad odor coming from the tank. We had to put the two fish back into their old tank with established media. I had to use bleach to get the stench of my hands. If your tank is not cycled, (and I suspect that it is not), move the fish to an established cycled tank, or do massive water changes and get some established media and some kind of bacterial additive for the tank. You need to get a test kit ASAP and record your ammonia, nitrite and nitrate readings on a daily basis until you know for sure that the tank is cycled. If I had a tank with the condition you describe, I would have no problem with doing two 50% back to back water changes every day until the water was clear and the parameters were good. Note: I am not telling you to do that, as there are people who would disagree. However, I would do it to my tank in a heart beat, knowing that was the only thing that would help if I didn't have another cycled tank to put the fish in. Also note: No amount of water changes will clear the cloudiness of a bacterial bloom, as the bacteria will keep reproducing. Increase your aeration. Using RO water for water changes could help. Here's an article on bacterial blooms.
