• Antibacterial polymer for internal infections of fish
• Use alone or mixed with other medications to make them palatable to fish and greatly reduce the loss of medication to the water through diffusion
• Treats fungal and bacterial infections

Focus is an antibacterial polymer for internal infections of fish. It may be used alone or mixed with other medications to make them palatable to fish and greatly reduce the loss of medication to the water through diffusion. For use in freshwater or marine aquaria.

Types of Infections Treated: Fungal, Bacterial

When to Use a Medicated Food Mix Your fish has an internal infection

Bloating, abnormal stools, loss of appetite, and weight loss are all signs of a potential internal infection.

You are already treating with a medication in the water

Sometimes fish will develop several infections at the same time, requiring multiple medications. We don’t recommend dosing two medications into the water, but it is possible to put one medication in the food and the other in the water.

There are corals, plants, or invertebrates in the tank

Using a medicated food mix will prevent damage to delicate plants or invertebrates from medication.

Directions Before Using

Focus should be combined with another medication to treat your fish’s specific infection. Research your fish’s symptoms to find the right medication for their disease.

Dosing in Food

Stir together the medicated food mix (recipe below) before feeding. Feed the fish once daily as much as they can consume in about 1 minute. Treatment periods will vary but it is recommended to treat for at least a week. This medicated food can be refrigerated or frozen between feedings.

• 1 scoop of medication if choice
• 1 scoop Focus
• 1 tbsp food (preferably pellets or frozen food)
• A few drops of water if using a dry food

Active ingredient: polymer bound nitrofurantoin (0.1%).

To enhance palatability use with GarlicGuard or Entice.

Treating common fish diseases with a medicated food mix

Ich (White Spot) 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: MetroPlex Blend: 14-21 days
Special 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.

Popeye (Bacterial infection)
Eyes protrude or appear to be "popping out" of the head. Popeye is caused by a buildup of fluid behind the eye and is often seen in conjunction with Dropsy. Suggested Treatment Period: KanaPlex Blend: 1 week

Hemorrhagic Septicemia (Aeromonas hydrophilia>
Reddish streaks in the fins near the body or under scales. Common in goldfish. Associated with overcrowding and stress, particularly in goldfish and koi. It can also be caused by a virus. Suggested Treatment Period: KanaPlex Blend: 1 week or SulfaPlex Blend: 3 weeks
Special Considerations - This infection is strongly linked to crowding and poor water conditions. Make sure your fish have clean water and plenty of space.

Dropsy (Symptom of internal damage)
Fish appears bloated, scales stick out in a pinecone-like manner. Dropsy is a result of damage to the liver, causing fluid to build up in the fish. It often starts as bloat and progresses to Dropsy over time. Suggested Treatment Period: KanaPlex Blend: 1 week
Special Considerations - Dropsy is a sign of severe internal damage, not a symptom of a specific disease. It is treatable with KanaPlex if caught early, but sometimes the damage is too severe to respond to medications. The best defense is to catch internal infections early, before they progress to this stage.

Mouth Rot (Columnaris)
Damaged fins, ulcers and yellowish patches on gills, tissue on head and mouth eaten away. This infection appears gruesome, but is entirely treatable. It is common to see fungus-like tufts around the face and mouth in addition to deterioration of tissue. It is essential to catch this disease early to prevent long-term damage. Suggested Treatment Period: KanaPlex Blend: 1 week
Special Considerations - Columnaris is very contagious. If possible, remove the infected fish to treat separately in a hospital tank.

Hole in the Head (Spironucleus)
Symptoms include a loss of color, erosion or lesions on the face, head, and body, and stringy white feces. This condition is often caused by an internal parasite, but factors like poor diet, poor water quality, and lack of trace elements will all contribute to this issue. Suggested Treatment Period: MetroPlex Blend: 2 weeks
Special Considerations - In freshwater this condition is called Hole in the Head. Research your fish’s preferred diet and water chemistry to ensure they are being properly duplicated in the aquarium. Consider using a nutrient soak for the food to provide essential vitamins and nutrients to the fish.
In saltwater this condition is called Marine Head and Lateral Line Erosion. It can be caused by an internal parasite, but more often these symptoms are connected to nutrient deficiencies or poor water quality. Duplication of the natural environment, proper filtration, and a nutrient-rich diet are all essential to curing this condition in saltwater.
