The test strips for aquarium water testing are horribly inaccurate. Pick up a freshwater Master test kit by API. They are available on Amazon, usually under $20. The readings from your test strips are odd, it indicates your tank has not cycled. If that is the case, cloudy water is common on newly setup tanks, it's a bacterial bloom. Be careful not to over feed, some foods will also contribute to fouling water. It's best to test your water frequently when setting up a new tank, and do a partial water change weekly at least 25 % An aquarium that has completed or cycled will usually have a nitrate reading, some say 20 ppm, if your dosing plant ferts, it will often be at least double.
