Blue Ribbon Pet Products ABLPLY4 Polyester Floss Bag Filter Media, 4-Ounce

Hard to find anything bad to say about filter fiber. I use is for hydroponic wicking reservoir not fish. I place a ball of this under plants as a back up to nutrient system supply failure.

This is probably the best for your money, physical filtration wise.

I have two nano tanks so this will last forever. I was having problems with my water being cloudy and this did the trick!!! Love it!

Used for years in my aquarium. Good product

Works perfectly as media helping to keep my turtle tank clean

Found it in the store for 65% less. Was very disappointed how much I over paid for a bag half the size and so much more money.

Great

Easy to use. You can use it in almost any type of filter. You can make it thicker than the cartridges that just slip in.

This killed my favorite goldfish in less than 24 hours! My brother is really upset

It filtered good.
