Review: A great weekly prevention/maintenance addition. - I like this stuff a lot. I’m new to the hobby and spend a lot of time in fish forums. This product was talked about a lot. And I knew I wanted to pick some up for water changes and/or stressful moments. I use all seachem products. But their stress product is more like a medication. It has a disinfectant in it. I was wanting something to chill the fish out and have healing properties. A slime coat product. This product fits that bill. So yes I am going to be adding it to every water change or new addition....basically once a week. At the time, my fish I had somehow...well say he bumped his head, ramming it into the gravel trying to get snail food. This healed it right up. And he noticeably calms down. He really does seem very peaceful after I add this. And it’s not temporary. His whole demeanor has changed. I like that this ia slime coat focused. I like the extra vitamins. I feel like a better fish parent because of this product. If ever a time comes that I need to medicate this product will be an obvious additions. It absorbs medications and sticks it on the fish. It’s just a great product. It’s a little odd that’s kordon isn’t as popular as it used to be. I’m glad I found this and was able to buy it. Review: Great stuff - The best polymer type "slime coat" product on the market. Binds great to meds, improves healing significantly, great just to toss in in addition to almost any other med. Occasional sore or something is the ideal use case for something like this. Wouldn't recommend the full amount regularly if you're an experienced keeper, healthy fish don't *need* products like this and I imagine you'll exhaust your chemical filtration more quickly. But still, another great product from the ogs, kordon. ## Features - ENHANCED HEALING: Adds a multi-layer slime coat, Vitamin B12 & Echinacea to help heal fish with missing scales, frayed fins, and bruises. Additional polymer colloids act as a carrier for medications, making them more effective. - EASES STRESS: Calms fish and eases stress, making it an ideal solution to protect fish and reduce fish loss during handling, illness, new introductions, and shipping. - SAFE & EASY: Safe for freshwater and saltwater fish, invertebrates, corals, live rock, and plants. Use in medication baths, quarantine tanks, or for added protection during handling and shipping. - DETOXIFIES: Removes all toxic heavy metals from the water, such as zinc, iron, lead, copper, and arsenic, which can be lethal to fish and invertebrates. - TRUSTED FORMULATION: Professional quality water treatment used by breeders, wholesalers, and public aquariums. Made in U.S.A., each 16 oz. bottle treats 960 gallons. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00412UDBE | | ASIN | B00412UDBE | | Allergen Information | Odor-Free | | Best Sellers Rank | #43,948 in Pet Supplies ( See Top 100 in Pet Supplies ) #421 in Aquarium Water Treatments | | Brand Name | Kordon | | Customer Reviews | 4.7 4.7 out of 5 stars (435) | | Date First Available | October 2, 2001 | | Department | Conditioners & Additives | | Global Trade Identification Number | 00048054314568 | | Included Components | Product in Description | | Is Discontinued By Manufacturer | No | | Item Form | Liquid | | Item Type Name | Kordon Fish Protector - 16 fl oz | | Item Weight | 16 Ounces | | Item model number | MODEL-31456 | | Liquid Volume | 16 Fluid Ounces | | Manufacturer | KORDON LLC | | Manufacturer | KORDON LLC | | Manufacturer Part Number | 31456 | | Model Number | MODEL-31456 | | Product Dimensions | 2.75 x 2.75 x 8 inches; 1 Pounds | | Target Species | Fish | | UPC | 048054314568 | | Unit Count | 16 Fluid Ounces | | Warranty Description | 1 year manufacturer | ## Product Details - **Brand:** Kordon - **Item Form:** Liquid - **Item Weight:** 16 Ounces - **Liquid Volume:** 16 Fluid Ounces - **Manufacturer:** KORDON LLC ## Images ![KORDON #31456 Fish Protector for Aquarium, 16-Ounce - Image 1](https://m.media-amazon.com/images/I/61GZINZcV5L.jpg) ## Questions & Answers **Q: What are the ingredients? Is it amine based? (Wondering because amines can be toxic with Purigen)** A: I don’t know of any ingredients outside of what’s printed on the label. However, as an avid & longtime user of Purigen, I have not noticed any ill effects after numerous regenerations. KORDON Fish Protector has always been compatible with Seachem’s Purigen to the best of my knowledge. **Q: Do i need to remove the tank's charcoal filter when using kordon's fish protector?** A: no I use this on every tank change never have taken out charcoal **Q: Does this product lower Ph or Kh?** A: Kordon Fish Protector does nothing to water parameters. It’s primarily used to replenish the fish’s slime coat and to aid medication absorption. **Q: Reef safe ?** A: Yes, it safe. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great weekly prevention/maintenance addition. *by K***E on September 16, 2018* I like this stuff a lot.
