Filt-A-Carb Replacement Activated Carbon Media Cartridges (2 Pack) – Fits Multi-Pore and Undergravel “E” Filters – Provides Chemical Filtration (FC2)

REPLACEMENT FILTER MEDIA: These Cartridges are made to fit the lift tubes of Muti-Pore and Undergravel “E” filters, serving as a replacement for when it’s time to cycle out aquarium filter media. We recommend replacing them once a month.

TOP-QUALITY CARTRIDGE: Cartridges come together in a 2 Pack. For best results, replace cartridges every 2 to 4 weeks. They’re lightweight, disposable, and are safe for Freshwater and Saltwater aquariums.

CHEMICAL FILTRATION: In addition to absorbing ammonia, nitrites, nitrates, and phosphates in a timely manner, these Cartridges also remove harmful chemicals and toxins, clear up discolorations, and reduce foul odors from your tank.

OLD SCHOOL: There has been a burst of growth, development, and ingenuity within the aquatic industry, and although we are a part of this as well, we still provide replacement media for undergravel aquarium setups.
