Regenerable with a simple bleach solution, Purigen offers sustainable, long-lasting performance trusted by thousands of aquarium enthusiasts worldwide. ## Description Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at an excelled rate and capacity. ## Features - FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water. - SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear. - CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin. - REGENERATION: Once Seachem’s Purigen is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics that have been removed from the tank. - SAFETY: Some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000255PJE | | ASIN | B000255PJE | | Allergen Information | Yam Free | | Best Sellers Rank | #10,212 in Pet Supplies ( See Top 100 in Pet Supplies ) #73 in Aquarium Water Treatments | | Brand Name | Seachem | | Customer Reviews | 4.7 4.7 out of 5 stars (3,670) | | Date First Available | June 20, 2004 | | Department | Unisex-Adult | | Global Trade Identification Number | 00000116016605, 00015568976827 | | Included Components | Purigen | | Item Form | Granules | | Item Type Name | Purigen | | Item Weight | 8 ounces | | Item model number | 166 | | Liquid Volume | 250 ml | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 75185 | | Model Number | 166 | | Number of Items | 1 | | Pet Type | Fish | | Product Dimensions | 4.9 x 2.4 x 2.3 inches; 8 ounces | | Target Species | Fish | | UPC | 015568976827 000116016605 | | Unit Count | 8.4 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Granules - **Item Weight:** 8 ounces - **Liquid Volume:** 250 ml - **Unit Count:** 8.4 Fluid Ounces ## Images ![Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 250ml - Image 1](https://m.media-amazon.com/images/I/61aCA7Ktx+L.jpg) ![Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 250ml - Image 2](https://m.media-amazon.com/images/I/714keBQlKFL.jpg) ![Seachem Purigen Organic Filtration Resin - Fresh and Saltwater 250ml - Image 3](https://m.media-amazon.com/images/I/81iuE4Wr7RL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Can use this in conjuction with avtivated charcoal,and im having a hard time trying to find media bag it for tetra ex70** A: You can! But honestly you don't need the carbon. Purigen does it all, it really works wonders. Keeps my tank clear and balanced. Can't say enough good things about it. The bags I use for this are called "Boyd Enterprises ABE16720 2-Pack Chemi-Bag" also on Amazon, $4.95 and you can rinse them out when you change the purigen and rescue them, my current ones are about a year old. **Q: Why can't this be shipped to my Puerto Rico address?** A: No problem shipping this to Puerto Rico. Buy from BPM Services. **Q: Would I be able to avoid the nitrogen cycle in my new 75 G. tank? I'm hoping it would just be a matter of getting the pH right. Thank You CRF** A: If you are setting up a saltwater tank you would not want to avoid the nitrogen cycle, in fact you want to establish the nitrogen cycle..ammonia, nitrite, nitrate, and I would not use purigen until you have high nitrate readings. If you are setting up a freshwater tank I do not know the answer. **Q: Iam dosing my tank with flourish currently. Would this remove those nutrients from the water?** A: No, I'm using it with R/O water and I'm doing great. I feel the nutrients are still present. ## Frequently Bought Together - Purigen & Matrix Bio Media 250ml - ALEGI Media Filter Bag Aquarium Extra Fine,Reusable 180 Micron Drawstring Mesh Filter Bags for Very Fine Resins Filter (7.5"*3.6" (3 Pack)) - Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml --- ## 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.us/products/3598893-seachem-purigen-organic-filtration-resin-fresh-and-saltwater-250ml](https://www.desertcart.us/products/3598893-seachem-purigen-organic-filtration-resin-fresh-and-saltwater-250ml) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-18*
