## Description

Seachem Kanaplex (Pack of 2)

Review: Important to have ready for emergencies - I recommend keeping some on hand for emergencies. I moved across the state recently and it was very stressful for my Betta. She developed epistylis about 3 days later, and quickly her health started to deteriorate! I knew I had to act fast and none of the stores near me carry Kanaplex specifically, which I wanted because it was recommended to me to try first. desertcart had it to me overnight which I am eternally grateful for because my fish began to recover after 3 days of consistent dosing both to the water and in food. Now she’s back to her usual self, all signs of epistylis are gone, and I’m glad i chose kanaplex. Safety: it is an antibiotic for an aquarium. Follow the directions on the back and everything will be fine. Plant growth: can’t speak on this one. I used a hospital tank so nothing was affected. Unsure on if it’s fully plant safe; I’d recommend googling your specific plant type to see if it could be negatively affected if you plan to dose your tank. Value for money: great value. I did not need a massive container, I only have a single Betta in a 10 gal. I really only needed 3 days of treatment but planned for 1 week just in case; I still have a little under half of the container filled after using 2 full doses for the hospital tank, and roughly half a dose for mixing with food which I then froze and took out tiny pieces to thaw as I needed. I fully believe that feeding it + dosing the tank is what led to a full recovery. Final verdict: Keep some of the common antibiotics on hand for emergencies, because when something does happen it sets in quick. Now I keep this product, some methylene blue and plenty of catappa leaves on hand. My fish is healthy and alive because I caught the epistylis quick and started treatment immediately.
Review: Saved My Guppy Fry - Over 30 one-month-old guppy fry in one of my aquariums started developing needle-like tails. In the morning, I noticed one of my fry had died overnight and several of my fry looked lethargic at the water surface with one fry floating on his side and struggling to remain upright. Now, while I'm no stranger to keeping freshwater fish, I just started keeping guppies a little over a year ago and this is the first time I've seen such a wide-spread infection with such a fast mortality rate. Admittedly, this tank in question was a bit overcrowded, since one of my female guppies gave birth a month ago with a surprisingly large batch of fry (for me at least). Since keeping guppies, finding spare tanks to keep each new batch of fry in has been a bit challenging. After testing the water for ammonia and finding close to 1ppm, I immediately separated four of the most lethargic fry into their own tank (since some of the more healthy-looking fry were trying to eat them) and spent the next two days performing large water changes. The fry only got worse, now with almost all of the fry displaying pointed needle-like tail fins even though water quality had considerably improved with 0 ammonia and nitrite. And sadly, another two fry that I had separated the first day hadn't made it. I was now left with one really sick fry (in the separate tank) and 28 less-than-active fry who looked like they were only getting sicker. A few weeks ago, I had purchased some Kanaplex to try for a just-in-case situation like this when time would be crucial. I had never used Kanaplex before, but I had lost some fish in the past because I wasn't able to get the medication quickly enough. I liked that this medication doesn't destroy the good beneficial bacteria in the filter bed, but I was very hesitant about using this in my fry tank because of how young and weak my fry were - I wasn't sure if they'd be able to handle medication. But I figured, they were already suffering and going to die if I just did nothing more than change the aquarium water, so I put some in and hoped for the best. Two days later, I already started to see some improvement. My fry were swimming more actively and I noticed some of them were starting to spread out their fins more. The lone fry in the really sick tank still looked somewhat the same to me, though he wasn't flipped over and paralyzed like many of his brothers who had died were. He was still swimming around the surface, moving his fins, so I thought that was a good sign. The best news was that I had lost no more fry since treating both aquariums. I had thought I would soon have a massive fry death on my hands, so that alone was something to celebrate. Following the instructions, I treated both tanks with the second dose of Kanaplex on the third day. Every day, the fry seemed to be doing better and better. Today on day 5, all 28 fry in the healthier tank are very active, eating as usual with fins fully expanded. Just looking at them, you would've never known they were sick! The lone fry in the separate tank is also doing very well. Just yesterday, he started eating for the first time since the infection. While his tail fin still looks somewhat pointy, the milky white film on it is nearly gone and it's no longer as clamped. I also noticed he's been spending less time on the surface and more time moving around the aquarium! Before I had little hope he'd make it and now I really do think he'll make a full recovery. I just added the third and last dose to the tank. I'm really looking forward to adding the lone fry back into the tank with his brothers and sisters. I also bought a larger aquarium to house these fry once they get bigger. Very happy with the results I've received from Kanaplex.

## 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 Focus™1 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.

### ⭐⭐⭐⭐⭐ Life saver!
*by M***A on February 27, 2026*

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
