(3 Pack) Fluval Edge Carbon Clean and Clear Renewal Sachets (3 Sachets Per Pack / 9 Total)

I use these in all my lil nano tanks. The keep the water clear for the entire month

It is carbon for turtle tanks. It works well, but turtles are still dirty animals.

The packets were smaller than I expected, but made sense for the price.

As described. Used for Flex 15.

Seems to be doing the trick, no complaints.

Same as OEM but much cheaper in bulk
