Acurel LLC 100-Percent Polyester Filter Fiber, 14-Ounce

Polyester pillow stuffing. Sadly, I could have gotten this numerous other places for half the cost. Live and learn. However, it is great stuff for fish filters.

This is a great quality product. I use this in my Biocube as an additional filter with the bio balls.

This is a great replacement the expensive carbon filled cartridges. If you remove the fiber and carbon from your old cartridges, you can use the plastic support to keep this floss in place in your filter. You only need the carbon to remove chemicals after treating for disease. This will save you a ton of money.
