Medic is a highly effective treatment for external fish parasites present in both marine and freshwater environments. It contains an antibiotic component and a reef-safe oxidizing agent that work together to help eliminate parasites. It is particularly effective against:
Many 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 medication to be most efficient during this stage.
Our medication targets the trophont stage of the parasite but is also very effective in disrupting the life cycle during the "free-swimming" stage. Thus, when using the medication, 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.
Directions for in Tank Treatment:
Use 1 level scoop of medic for every 50 gallons (190 liters), twice per day
**Serious problems, use 3 level scoops
Dose once in morning and once in evening
Continue dosing for 10 days, and up to a maximum of 20 days
Note: Ozone and carbon must not be used during the treatment
Protein skimmers can be run as as normal
UV filter can be used one hour after dosing
The problem 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 minimum entire course (10 days) to be maximally effective
After treatment is complete, run granular activated carbon for 2 or 3 days

Great product that works. You must follow the direction to the tee. I use it in the maximum dose 2 X's a day for 20 days as directed. I put the meds into a small glass with system water and crush the little crystals till they are dissolved. It does work but takes time be cause of the parasites life cycle. That is why 20 days is required.Hide
I introduced a fish that developed ich. The Polylab did not save that fish, but my Purple Tang had started to get a bit of the ich and the PolyLab put an end to that! Been safe for my corals except where the undissolved granules fall.

I wish I had the same results as the other reviews, my dijardini tank got ich when my feeder failed and I turned to this product which I hear was the best. Unfortunently it took 17 days to clear my tank of ich and in doing so managed to completely wipe out my two rose anemone as well as all of my coral save 1 mushroom. Very disappointed in over several hundred dollars of coral loss. I would give 1 star except my dijardini survived and isnlooking healthy. Thanks, I guess...Hide
Had a nasty case of ick on my tank. The thankfully this product saved the day and save me some stress of fish loss. Love how it has minimal effect on my coral too.
