Each 2-pack contains two wool carbon cartridges that drop directly into either filter housing with no modification. The wool layer captures suspended waste and particulates while the carbon layer clears discoloration and dissolved organics, restoring both mechanical and chemical filtration capacity in a single swap.\u003c\/p\u003e\u003cp\u003eOne cartridge size covering two filter models simplifies restocking for hobbyists running multiple tanks. Whether you have an SF-240 on a shrimp tank and an SF-500 on a planted community tank, a single pack covers both. Replacing on a 3 to 4 week schedule keeps flow consistent and prevents the media from becoming a source of nutrients rather than a remover of them.\u003c\/p\u003e\u003ch3\u003eKey Features:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003eFits both the Dymax Slim Flo SF-240 (5–8 gallon) and SF-500 (10–24 gallon) filter models\u003c\/li\u003e \u003cli\u003e2 cartridges per pack for back-to-back scheduled maintenance without a restock gap\u003c\/li\u003e \u003cli\u003eWool carbon construction handles mechanical and chemical filtration in one replaceable unit\u003c\/li\u003e \u003cli\u003eDrop-in fit requires no cutting or modification to the filter housing\u003c\/li\u003e \u003cli\u003eRemoves suspended waste, particulates, and water discoloration\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003eIdeal For:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003eHobbyists running both an SF-240 and an SF-500 who want to stock one cartridge size for both units\u003c\/li\u003e \u003cli\u003eSF-500 owners running planted tanks or community tanks up to 24 gallons on a regular maintenance schedule\u003c\/li\u003e \u003cli\u003ePlanted tank keepers who want a straightforward, low-cost media refresh with no DIY cutting or fitting\u003c\/li\u003e \u003c\/ul\u003e\u003ch3\u003ePro Tips:\u003c\/h3\u003e\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eOne pack covers both filters if you run an SF-240 and an SF-500.\u003c\/strong\u003e The Medium\/Large cartridge is interchangeable between the two models.
