MetroPlex™ is an effective and safe treatment for several protozoan and anaerobic bacterial diseases of fish (Cryptocaryon, Hexamita, Ichthyophthirius). It does not adversely affect the filter bed and is easily removed with carbon. It can either be dosed into the water or combined with Focus™ in a medicated food mix. It will treat both internal and external infections regardless of the delivery method. When used in a medicated food mix, it is excellent for treating parasites in tanks that contain invertebrates. MetroPlex is gentle and there little danger of overdosing.

Directions
Dosing in Water
Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon™ and Purigen™. Use 1-2 measures (included) per every 40 L (10 US gallons). Repeat this dose every 48 hours for up to 3 weeks or until symptoms disappear.
Dosing in Food
Feed the medicated food mix (recipe below) every day until the infection clears or up to 3 weeks. This medicated food can be refrigerated or frozen between feedings.
To enhance palatability use with GarlicGuard™ or Entice™.
After Treating
When the treatment period is over, MetroPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank.

Treatable Diseases
Common Fish Diseases Treatable with MetroPlex
Ichthyophthirius (freshwater) / Cryptocaryon (saltwater)
Looks like salt sprinkled on the fish’s body and fins. Usually accompanied by twitching, flashing, and other signs of stress and irritation. Several parasites are grouped under this name, but the symptoms are almost identical. Ich is among the most common infections of fish, and is entirely treatable with diligence and attention to water quality.Suggested Treatment Period:
14-28 daysSpecial Considerations
It is very important with this parasite to continue dosing for the full treatment period. A break in the medication allows the parasite to multiply and reinfect the fish.They’re not always on the fish!
Ich, velvet, and many other parasites spend a large portion of their life cycle as a cyst that is immune to medication and hiding in the substrate of your tank. Remember that you need to finish the full treatment even if you can’t see parasites on the fish any more!
