| I've used the polyfilter in my marine tank and was impressed with how well it worked. It cleared up the yellowing in my water very quickly and much more effectively then carbon did. It's also good for absorbing toxins in the water.
It's an expensive filter pad, but I have one at home at all times in case of emergencies. They are very good filter pads!
