I dont know TM reef product.
I think FM hasnt any product of proteolytic enzymes...
Perhaps the FM product what you are talking about is Ultra Life, this product is clay...
And zeozyme I am sure it is proteolytic enzymes.
Proteolytic enzymes break proteins in aminoacids...
Proteolytic enzimes are proteins too, if skimmer is on then they will be easily removed by skimmer.
