Whisper Tetra AQUARIM FLTR CRTRDGS Box 3 CT - 0046798262181
Ready to use Tetra Whisper Cartridges make clean water simple and efficient. Ultra-activated carbon absorbs odors and discoloration while dense, dual sided mesh catches debris and fish waste to keep water crystal clear.
Instructions: 1. Rinse filter cartridge under cool tap water to remove carbon dust. 2. Open lid and insert filter cartridge into filter. 3. Replace clogged filter cartridge when there is reduced water flow out of the filter. For best results, change filter cartridge monthly.
