Starting up a new reef tank. I've been using Coralife scientific grade salt for a long time with tap water and never had any problems with cloudiness. Now I'm using RO/DI water. So I mixed in the appropriate amount of salt to 5 gallon jugs a few days ago, added the water to my tank, turned on the heater and a few power heads to mix, and my new tank has been cloudy for 24 hours with a white film on the glass. One other thing that might be important, my bucket of Coralife salt had hardened (solidified) so I had to chop it up with a knife before adding it to the water. Did the salt mix go bad (I've had the bucket for well over a year)? Any ideas? Please help!
