I think TimT who is a vendor here may be able to explain this as i am pretty sure that is what is in his phoz down product(if i am assuming correctly). I have tried a product with this in past and liked the result but am waiting for my new doser to come in before i try it again as dosing daily is a bit tedious. But when using it the only down side i found was filter socks plugging faster.
