While the tank is cycling, it will get a little cloudy like you say it is. I'm cycling my 55G, was crystal clear, now a little cloudy. But that's due to the bacteria blooms. I'm currently going through the nitrite spike, so that's the reason of my bacteria bloom. Once the tank cycles, it should clear up when you have all the proper bacteria in place.
Also, don't use the Amquel Plus, I think Aquaplus is ok though. Prime is good for sure. Also, Cycle really doesn't do anything. About the only product that does is Bio-Spira. And has to be refrigerated at all times, and best to use right away. Not a very long shelf life.
