White film

[N1Husker]

I seem to have developed a white film on the surface of my water. You can’t see it from the top, but it is prevalent when you look from the bottom. I recently switched salt mixture to Aquacraft Bio Marine Salt Mix. That’s the only thing I’ve done different. I contacted the owner, Michael De Preet, he said they don’t put anything in their salt to cause a film, so I don’know. Any ideas. I treat with a bag of Phosgard and dose Red Sea NO3PO4. Any ideas?

Try and going back to your old reliable salt mix and see, maybe it had an unknown reaction to something in your tank.

Yeah, I don’t know what was, but it has disappeared. I did a couple of water changes and that seemed to help. I am still using the new salt and my corals seemed to really respond positive to it.
