I have been using Accurel media pads in my Marina S20 filter for about a year. Cut to size, it fits easily into the filter slots. It's rigid, which makes it very easy to slide into place. It also appears to be tighter woven than other media pads, so it catches even the tiniest bit of debris. I also have Purigen in my filter and on the back of the filter I use an Accurel ammonia reduction pad which I also cut to size. Since I only use one portion at a time, a large pad is inexpensive. The water in my 5-1/2 gallon aquarium stays perfectly clear and the fish stay healthy. I prefer the white Accurel backing over the standard blue and white style due to the stiffness and density. Just make sure to rinse it well before putting it in the filter to remove any loose fibers that might be stuck to it.
