Each one has a dense, dual-sided mesh designed to trap debris and fish waste as water passes through, while the carbon inside helps keep the water clear. Swapping in a fresh cartridge is a simple part of routine tank maintenance.\u003c\/p\u003e\u003ch3\u003eReady to drop in\u003c\/h3\u003e\u003cp\u003eThe cartridges arrive fully assembled, so there is no need to fill bags with carbon or cut media to size. Tetra colour-codes its packs to help you pick the correct size for your filter, and this pack contains the large size.\u003c\/p\u003e\u003ch3\u003eWhat comes in the pack\u003c\/h3\u003e\u003cp\u003eThe pack holds three large Bio-Bag filter cartridges. With a monthly change, that is roughly three months of replacements for a single filter.\u003c\/p\u003e\u003ch3\u003eHow to use\u003c\/h3\u003e\u003cp\u003eRinse the cartridge under cool tap water to wash away loose carbon dust, then fit it into the filter. Replace it monthly, or sooner if water flow drops, as the carbon loses effectiveness after about 30 days.\u003c\/p\u003e\u003ch3\u003eBefore you choose\u003c\/h3\u003e\u003cp\u003eThese cartridges are designed for Tetra Whisper filters, so check that the large size matches your filter model before ordering.
