Polyplab Medic (30ml)

Medic is a much respected and highly effective water conditioner and reef-safe oxidizing agent, and is particularly effective against:

Marine Ich – Crytpocaryon irritans
Freshwater Ich – Ichthyophthirius multifiliis
Marine Velvet – Amyloodinium ocellatum Features • Completely reef-safe
• Buffered to maintain physiological pH
• Does not harm invertebrates
• Does not harm nitrifying bacteria

Size: 30Ml – (Treats 550G of aquarium volume)

How Medic works: 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 conditioners do not affect the free-swimming stage of the parasite which is one of the primary difficulties in dealing with these infections.

Research with ciliated protozoa 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 effectively conditions the aquarium water to inhibit all stages of the parasites life cycle, but is also very effective in disrupting this cycle during the “free-swimming” stage. Thus, when using Medic, hobbyists should try to maintain the highest concentration of the conditioner during this “free-swimming” time frame – when the oxidative component in the conditioner is particularly effective against theronts/dinospores.

Active Ingredients: Crystallized Peroxide Salts. Directions for use:

Use one level scoop of Medic for every 50 G (US) of your system volume twice per day. 1 USG = 1.2 UKG
Add once in the morning (Before 10am if possible).
Add once in the evening (After 10pm if possible).
Continue to add for 10 days.

Note: UV, ozone and carbon must not be used at any point throughout the 10 day cycle. However Protein skimmers can be run as normal.

The degree of infestation 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. Therefore you must continue adding the Conditioner for the entire course (10 days) for maximum effectiveness.

After the 10 day course is complete, run granular activated carbon for 2 or 3 days.

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