Review on MarineLand Activated Chemical Filtration Aquariums by Margarita Conde

Great product. Excellent price. I use them in my Marineland c-220 canister filter. I first bought loose charcoal to save money. What a mess! I quickly switched back to bags and couldn't be happier. They're sold as add-on items, but if you buy 2 of each (aqueous floss and filter foam) at a time, you hit the $25 threshold, which will last you a couple of months. To all the reviewers who said it was dirty, I guess they've never looked at carbon. It needs to be washed. But it's a lot cleaner and easier than loose charcoal and I highly recommend this product.
