The cloudy water means the cycle is "working". Don't add any more of the clarifier--it's best not to add unneeded chemicals to the aquarium. Same goes for any chemicals like algae killers, ammonia removers, etc. If there's a problem, like cloudy water where it's not normal (in a tank that's already cycled), then it's best to figure out what's causing it and address the cause (maybe it's overfeeding, or not enough water changes) rather than adding chemicals.
Also you don't need to use both Prime and Stress Coat at the same time--they both dechlor the water so basically their function is redundant. During cycling Prime is important because it turns some of the NH3 & NO2 into forms that won't hurt the fish. Stress Coat contains aloe vera which may be beneficial to the fish when they're stressed--if that's why you're using it, that's fine. But just letting you know you don't need to keep using one or the other once the tank is cycled.
