## Description

Because it is absorbed by fish it is useful in treating internal infections in those situations where food is refused. It does not adversely affect the filter bed and is easily removed with carbon. To enhance palatability use with GarlicGuard™. Food may be refrozen. For use in freshwater or marine aquaria.

Review: fast delivery and nice product - it's in a safe box, so the items are very secure, and they deliver very fast.
Review: This product saved my bettas life! He had dropsy and was in very rough shape. I started the meds 4 days after noticing but did Epsom salt baths and daily partial water changes until it arrived. I was convinced I was going to lose him but 24 hours after the second dose the swelling started to go down, and now 48 hours after the full course of medication he is almost fully recovered! Sooooo thankful for this medication. I will always keep it on hand now. Included photos of before and after treatment

## Questions & Answers

**Q: How many gallons does one container treat? I need to treat 240 gallons.**
A: Each level scoop is 125mg and treats 5 gallons for 1 day's dose. There are 40 scoops in the 5 gm vial.  5 grams would treat 200 gallons for 1 day's dose.

**Q: Hi! my betta got popeyes. i bought this but don't know how to use it. it says it goes with frozen food paste.could you tell me where to get the food?**
A: as per the manufacturer......KanaPlex is a blended kanamycin based medication that safely and effectively treats several fungal, and bacterial fish diseases (dropsy, popeye, fin/tail rot, septicemia). Because it is absorbed by fish it is useful in treating internal infections in those situations where food is refused. It does not adversely affect the filter bed and is easily removed with carbon. When used in a medicated food mix, it is excellent for treating bacterial infections in tanks that contain invertebrates. For use in freshwater or marine aquaria.Types of Infections TreatedParasitic	Fungal	Bacterial	ViralKanaPlex				DirectionsDosing in WaterRemove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon and Purigen. Use 1 measure (included) per every 20 L (5 gallons). Repeat this dose every 48 hours to a maximum of 3 doses. In cases of severe infections, it is possible to carry out two rounds of treatment back-to-back. However, this should only be done if fish show no signs of stress at the end of the first round.Dosing in FoodFeed the medicated food mix (recipe below) every day until the infection clears or up to 1 week. This medicated food can be refrigerated or frozen between feedings.1 scoop KanaPlex1 scoop Focus1 tbsp food (preferably pellets or frozen food)A few drops of water if using a dry foodTo enhance palatability use with GarlicGuard or Entice.After TreatingWhen 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.

**Q: Do you have to treat food with it to administer or can I just treat the water directly?**
A: The manufacturer instructions are: "Use 1 level measure (included) to every 20 L (5 gallons). Repeat every 2 days until symptoms disappear or up to a maximum of 3 doses. Turn off UV, ozone, and chemical filtration. To feed, blend 1 measure with about 1 tablespoon of frozen food paste. To minimize loss during feeding use with Focus. To enhance palatability use with GarlicGuard or Entice. Food may be refrozen.Active ingredients: kanamycin sulfate (32%) Inactive ingredients: excipients (68%)"

**Q: Is this enough to treat a 29g tank 3 times?**
A: Yes, I personally was able to treat my 55g tank with it at least three times.
