Activated Carbon Filter Bags — 20 Pack

Pre-portioned mesh bags of activated carbon for when water looks tinted, smells swampy, or after any medication course. Drop one in, pull it out a month later, done.

• Clears the yellow. Carbon adsorbs the tannins from driftwood and leaf litter that water changes alone will not shift quickly.
• Medication clean-up. Standard step after finishing a treatment course — one bag removes the residue from the water column.
• No mess, no measuring. Each portion is bagged, so nothing spills into the tank and there is no rinsing loose carbon.
• Replace monthly. Carbon exhausts; an old bag does nothing. Twenty bags is a twenty-month supply for most nano and mid-size tanks.
