cloudy water in blue crayfish tank

[fishums]

I have ten gallon tank with a small blue crayfish in it. I have only had it running for a few days and its getting cloudy. I filled it with water from my 55 gallon cichlid tank and put a filter in it that has been used in a established tank. When i test it it reads little to no ammonia. What could possibly be the cause of this?

My guess would be bacteria bloom. Happens with all newly established tanks and usually dissappears within a week.Maybe a little longer on large tanks.
It is a good sign .
