How Medic worksMany external fish parasites have very similar life cycles. In particular, these parasites have an "attached" stage (trophonts), a "matured" stage (protomonts), a "reproductive" stage (tomonts), and a "free-swimming" stage (theronts/dinospores). Most available treatments do not target the free-swimming stage of the parasite which is one of the primary difficulties in dealing with these infections.


Research with ciliated protozoans has shown that the "free-swimming" stage of these parasites have remarkably consistent hatching times. We have engineered our product to be most efficient during this stage.


Medic targets the trophont stage of the parasite but is also disrupting the life cycle during the "free-swimming" stage. Thus, when using Medic, hobbyists should try to maintain the highest concentration of the medication during this "free-swimming" timeframe - when the oxidative component in the medication is particularly effective against theronts/dinospores.

Use one level scoop of Medic for every 190L of your system volume twice per day.

Dose once in the morning (Before 10am if possible).
Dose once in the evening (After 10pm if possible).
Continue to dose for 10 days.


Note: UV, ozone and carbon must not be used during the treatment. Protein skimmers can be run as normal.


The infection may seem to disappear when white specks are no longer visible on the fish. This is merely part of the natural cycle of the parasite and you must continue dosing the product for the entire course (10 days) to be maximally effective.


After treatment is complete, run granular activated carbon for 2 or 3 days.


Store product in a cool and dry location, away from direct sunlight.
