My fish tank is stinky and cloudy how do I fix this?

I don't know if it's the nitrates or not but ever since the first day it's been cloudy I've done a 10% water change and a 100% water change but it's still foggy. I've changed the filters and washed every piece of the equipment but the fog won't go. I've only had this take for 8 days. I have three angle fish and one sucker fish. My tank is a ten gallon I don't know what to do please help.
