Long term Effectiveness: Praz-Pro

[jnc914]

I use Prazi-pro religiously when treating for fluke with the angels and butterflies in my tank. For the most part I believe it is highly effective, however I question how effective the medication is after the first 2-3 days of it being in the tank. It is recommended that you do a 5-7 day treatment, but realistically, is the medication really doing anything after the inital dose? The reason I ask is I have recently used it on a Male Scribbled Angel after I saw him flashing, twitching and scratching. I think that the Prazi likely killed off the adult fluke within the first 24-48 hours, but I am sure there are eggs still lurking. I intend on running another Prazi treatment to make sure I get all of the fluke. I just feel that Prazi likely dissolves and becomes less effective as the 5-7 day treatment cycle passes. Any one else have their own input on this? :mixed:

I am unsure as to the effectiveness of the drug after the first couple of days, but I am unable to run my skimmer after 5 days without a water change b/c of the massive foaming that occurs.

The standard praziquantel treatment is two additions, (with water changes) spaced out to break the life cycle of the fluke being targeted - frequently it is dose, wait 7 days, water change, re-dose, wait 7 days and then a final partial water change/turn skimmer back on.
I don't know why Prazipro suggests just one treatment, surely they must have learned something from the marketing genius that came up with "lather, rinse, then repeat" effectively doubling shampoo usage and also sales(grin).

Seriously though, not all flukes lay eggs - livebearing species might get knocked out in one treatment, but since most aquarists can't determine which fluke they have, it seems to me that a double treatment would be prudent.

You can definitely use Prazi in a tank with live rock. I have used Prazi in my display and in QT that has rock in it. It claims to be safe for inverts, however I lost two cleaners during the second week of treatment. In my mixed reef the corals did not like the Prazi, but nothing died because of it.

Jay---Thanks for the input. I usually try the method you described. I just thought it might be as effective or more effective if I did a water change and redosed after the third or fourth day if the Prazi begins to dissolve or weaken in the system. At the same time I don't want to over stress the fish and possibly lend to its demise.
