This advanced biological filtration media enhances the nitrification cycle, ensuring superior water quality with minimal maintenance, making it a top choice for aquarium enthusiasts seeking reliable and efficient filtration. ## Description Evolution Aqua K1 filter media is a high performance filter media that provides a large protected surface area. K1 Media provides protected surface area to boost beneficial bacteria colonization for biological filtration. As the K1 Media moves within the filter, it causes old bacteria on the outside to be displaced. This makes space for new, younger, heavier-feeding bacteria to rapidly colonize. Within the wheel is a protected surface which enables colonies of bacteria to naturally follow their lifecycle and then fuel the latter stages of the nitrification cycle. Designed to be self-cleaning. ## Features - Nonstop Contact - Automatic Cleaning - Safeguarded Surface Area ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00AHA4ZYK | | Best Sellers Rank | #364,877 in Pet Supplies ( See Top 100 in Pet Supplies ) #5,468 in Aquarium Filter Accessories | | Brand Name | Evolution Aqua | | Customer Reviews | 4.6 4.6 out of 5 stars (167) | | Item Weight | 250 g | | Liquid Volume | 50 liters | | Manufacturer | Evolution Aqua | | Manufacturer Part Number | MEDIAK1/50 | | Model Number | MEDIAK1/50 | | Pet Type | Fish | | Unit Count | 1 Count | ## Product Details - **Brand:** Evolution Aqua - **Item Weight:** 250 g - **Liquid Volume:** 50 liters - **Number of Packs:** 1 - **Unit Count:** 1 Count ## Images ![Evolution Aqua K1 Media - 50 Liters - Image 1](https://m.media-amazon.com/images/I/31qdbhhByfL.jpg) ## Questions & Answers **Q: Is this real evolution aqua k1? i bought media advertised as k1 on amazon & it's bigger than the real k1 i already have so it's a knock off.** A: Thanks for your question! Anything sold as Evolution Aqua K1 Media ought to be the authentic material, so I sympathize with you that you received an inferior item. While I cannot speak for every seller on this listing, we purchase directly from Evolution Aqua USA, so you can be confident that what we offer is the genuine media. — Steve at Practical Garden Ponds, 484-237-2080 **Q: is this 25 or 50 liters? and how much many bags would it take to fill a 55 gal barrel?** A: This listing is for 50 liter. How much it would take to fill a 55 gallon barrel partly depends on how tightly you want to fill it. If you are making a moving bed, the secret to success is that it is loose and can move. Liquid to liquid, there are about 208 liters in a 55 gallon drum, but it would require less than that to do it loosely. Feel free to call with additional questions. Sincerely, Nate at Practical Garden Ponds 484-237-2080 option 1 **Q: how many pounds of the K1 media is in this 50 liter bag?** A: Hello joe, thanks for asking! There are roughly 14 Lbs in a 50L K1 Media Bag. I hope this is helpful! Dana at Practical Garden Ponds, 484-237-2080, ext.1 **Q: I have a sand filter for my (small) pond. Can I replace sand with this material? Does this material have a longer life than sand?** A: Thank you for your interest. There is more difference between a quality Pond Filter and a sand filter than just the media. The laterals in a sand filter have very small perforations so that the sand does not escape. Therefore, with a sand filter, even if you replace the sand with a good quality "bead filter media" your filter will still clog more frequently with dirty pond water than you will likely appreciate. It would be well worth your while in the long run to buy a K Plus Pressure Filter with all of the arts to begin with. Filters and the laterals in them are designed for different medias and different flow rates etc. You can make your own filter and use one of many medias but your results will be less predictable and won't come with engineering specifications that you can count on. Results will vary.
