My betta fish, Bluey, had a pretty bad case of fin rot, and his fins had several holes and damaged areas. After following the directions and completing the treatment, I started noticing new fin growth. His fins are filling back in beautifully, and the damaged areas have almost completely recovered. Even better, he’s much more active, alert, and seems happier overall. I’m so relieved I found this product. It truly helped my fish recover, and I would definitely recommend it to anyone dealing with fin rot. It made a huge difference for Bluey. Review: Recommend - Worked for purpose needed. Clean product. Easy to use. Simple instructions. Has measuring spoon attached to lid which is convenient. Safe to use in water column or mixed with food, at least in my experience. I prefer to just put in water. Doesnt spill or leak. Last for many uses. Improved fish health. ## Features - KanaPlex is a blended kanamycin based medication that safely and effectively treats several fungal and bacterial fish diseases (dropsy, popeye, fin/tail rot, septicemia) - Good for treating internal infections in situations where food is refused - Does not adversely effect the filter bed and is easily removed with carbon - Good for use in Marine and Freshwater aquariums - Pack of 2 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LASJTJE | | Allergen Information | Codfish Free | | Best Sellers Rank | #1,973 in Pet Supplies ( See Top 100 in Pet Supplies ) #6 in Aquarium Water Treatments | | Brand | Seachem | | Brand Name | Seachem | | Customer Reviews | 4.6 out of 5 stars 4,006 Reviews | | Included Components | Kanaplex (Pack of 2) | | Item Form | Powder | | Item Type Name | Kanaplex (Pack of 2) | | Item Weight | 5 g | | Manufacturer | seachem laboratoried | | Manufacturer Part Number | 881 | | Model Number | 881 | | Number of Items | 2 | | Number of Packs | 2 | | Pet Type | Fish | | Target Species | Fish | | UPC | 000116088107 | | Unit Count | 1 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Powder - **Item Weight:** 5 g - **Number of Packs:** 2 - **Unit Count:** 1 Count ## Images ![Seachem Kanaplex (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/71yzZQH9-xL.jpg) ## Available Options This product comes in different **Size** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ⭐⭐⭐⭐⭐ Amazing results for my betta’s fin rot *by S***A on June 19, 2026* I honestly wasn’t expecting such great results, but this medication exceeded my expectations.

Last for many uses. Improved fish health. ### ⭐⭐⭐⭐⭐ Important to have ready for emergencies *by C***J on November 29, 2025* 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. Amazon 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. ## Frequently Bought Together - Seachem Kanaplex (Pack of 2) - API AQUARIUM SALT Freshwater Aquarium Salt 67-Ounce Box (Packaging May Vary) - API MELAFIX Freshwater Fish Bacterial Infection Remedy 16-Ounce Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/14273994-seachem-kanaplex-pack-of-2](https://www.desertcart.is/products/14273994-seachem-kanaplex-pack-of-2) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-22*
