Here's my usual QT procedure:
Prophylactic Treatment: No observed symptoms of disease or injury
20 gal QT cycled:
- HOB with both the foam pad & BioMax treated with Seachem Stability or Bio Spira/Dr Tims, and foam bubble filter with foam soaked in the same, or all of them soaked for at least 2 weeks in DT sump.
- heater, powerhead, Seachem Ammonia Alert Badge.
- Tank lights off. Ambient room lighting only.
- Feed fish high quality fiber packed frozen food (LRS or your own "fish smoothie") with Selcon/Zoecon added for at least 3 days
- Freshwater dip to check for flukes. If no flukes treat first with copper.
- S-l-o-w-l-y (5-7 days) bring up copper to therapeutic levels for prophylactic treatment for 30 days: Tank lights off until therapeutic level is reached. Best to dose several times a day (AM, lunch, PM) rather than one large dose. Highly recommend use of Copper Power and a Hanna HL Copper Checker.
- Carbon & Cuprisorb to remove copper. Water changes. Observe.
- General Cure 2 doses 5-7 days apart. Turn up bubbler and turn on powerhead aimed at surface to increase O2. Like GC over Prazipro. GC has Metro + Praziquantel, so you are getting the Praziquantel which kills flukes and "some" internal parasites and Metro that kills all internal parasites/worms. And the dose of Praziquantel is lower but does the job and is easier on sensitive fish.
- Carbon & water changes.
- Observe 10-14 days.
