Ok so my mom and I went to Home Depot about 3 weeks ago because she needed an air condtioner filter. She couldnt find the right size, so she bought those cut-to-size filters. So I took the rest. It is blue in color and looked like it would be a great idea for a filter cartridge. I cut 4 circles the size of my Eheim and put 4 layers in there and put 1 on each side of my Penguin 350.
These things have been great! My tank is so clear now. It was before, but I have noticed an improvement in the clarity of my tank. The thing was 9 dollars, but well worth it. I noticed NO ill effects on my tank and fish, and all I had to do to "prepare" it for my tank was rinse it under the sink first.
So I recomend instead of filter floss or filter cartidges that this be used. It was a great experiance.
