I was able to cut 44 pieces to fit my Marineland C220 filter. It is thicker than the Marineland pre cut polishing pads. I am running 2 of these filters on my tank so if you do the math with monthly changes, that is almost 2 years of maintenance at a cost of $10. The combination of this and Dr. Foster and Smith's activated carbon will save me a lot of money in maintenance costs.

Easy to use, just tear off the amount or size you need. I use it before my bio rings in all my filters. It is very inexpensive and last for months if you rinse it out before it gets too dirty. A small bag lasts for months.

The filter wool works flawlessly, does it exactly what I wanted it to do. It's priced very low which is great. But yeah, it really is a great product. I put it in my Penguin Bio-Wheel 200, and just putting the floss on the interior intake makes a dramatic difference,
Anyways, no problems here, product works great.
Thanks for the follow up/
