I think it is the Turtle Clean that has caused this... it is the only thing in the tank that has changed.
I ran out of one bottle and bought another. The issue started after this. I make sure to shake well and only put the reccomended amount in. A film-like substance is created on top of the water. It looks like something has seperated. It appears almost like oil and water.
Attached is a picture that sort of shows it.

Has anybody else experienced this, knows for sure what causes this or how to fix it?
I've never had a problem with the turtle clean before, perhaps I got a faulty bottle?
