Prazipro in the reef - once and for all

[tytown]

thanks everyone,
hfp75, are you able to share the literature you speak of stating it will kill your worms and feather dusters? They say the following: "There are no known contraindications to the use of Liquid PraziPro except for use in marine (saltwater) systems where flatworms of the Polycladida order are being cultured."
I dont believe bristle worms and feather dusters are members of the polycladida order.
freezetyle, what is this "therapeutic" dose you speak of? The manufacturer only describes one treatment method of 5 ml per 20 gallons for 5-7 days.
I would be interested to hear what dose you did and how you found it worked.
