It seems unlikely to me that phosphate would cause the problems you observed, 
but then I don't know what would cause those problems so I suppose that one 
guess is as good as another.

Per manufacturer's recommendations, you would probably want two bags of 
flourite in a 20 gallon tank.   I think that makes a fairly shallow 
substrate.  You might want to pump it up a little with a layer of gravel over 
or under the Flourite, depending on what you want to be most visible.
