• 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. Focus is primarily intended to be mixed with food and/or 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.

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.

Active ingredients: Active ingredient: polymer bound nitrofurantoin (0.1%).

Compatibility

Safe in reef tanks, planted tanks and with invertebrates — because it is fed rather than dosed into the water, it does not touch the rest of the system.

Focus is a binder, not a medicine. It carries another Seachem treatment into food and keeps it there rather than letting it leach into the tank.

Dosage & Directions

Mix one measure of Focus with one measure of the medication and one tablespoon of food, moistened with a few drops of water. Feed once a day, giving only as much as the fish clear in about a minute, for at least a week.

Refrigerate any medicated food you have made up and discard what is left at the end of the course.
