Replacement Filter Cartridges for the Dymax Slim Flo SF-120

The Dymax Slim Flo Filter Cartridge (Small) keeps your SF-120 running at rated flow between maintenance cycles. Each 2-pack contains two wool carbon cartridges that drop directly into the SF-120 filter housing with no cutting or modification. The wool layer traps suspended particulates and the carbon layer handles discoloration and dissolved organics, so both mechanical and chemical filtration get refreshed in a single swap.

Having a spare on hand matters more for small tanks than large ones. In a 1 to 4 gallon system, a clogged cartridge reduces flow faster and affects water quality sooner than it would in a larger volume. Keeping a second cartridge ready means you can swap on schedule rather than waiting for a new shipment.

Key Features:

  • Sized specifically for the Dymax Slim Flo SF-120 filter (1–4 gallon tanks)
  • 2 cartridges per pack for back-to-back scheduled maintenance without a restock gap
  • Wool carbon construction handles both mechanical filtration and chemical polishing in one unit
  • Drop-in fit requires no cutting, trimming, or modification to the filter housing
  • Removes suspended waste, particulates, and water discoloration

Ideal For:

  • SF-120 owners on a regular 3 to 4 week cartridge replacement schedule who want a spare ready to go
  • Nano planted tank keepers who run a shrimp colony and need consistently clean, clear water in a small volume
  • Hobbyists who buy consumables in advance to avoid going without filtration media between orders

Pro Tips:

  • Swap the cartridge before you see a flow drop, not after. In a 1- to 4-gallon tank, a partially clogged cartridge affects water quality before you notice any visible change in flow. Set a calendar reminder every three to four weeks and replace it on schedule.
  • Rinse the filter housing when you swap the cartridge. A quick rinse of the plastic housing removes trapped debris that would otherwise re-enter the tank with the fresh media in place. Do not use soap; plain water is enough.
  • Do not clean and reuse the old cartridge. Washing a spent wool carbon cartridge releases the captured waste back into your water and degrades the carbon. A fresh cartridge from the 2-pack is the right move.
