Fish tank water cloudy?

I just got a new filter for my 10 gallon fish tank because the last one my fish kept getting stuck behind it and they couldn’t get out. Even so that problem is fixed I got the top fin 10 gallon filter that hangs on the top instead of inside. Now the waters cloudy and I added some prime to help it out but I’m not sure if it’s the filter.


That's normal for an uncycled tank without a healthy biologically active filter. You might find other questions asking about "why is my tank cloudy", maybe that would be a good place to start .
