Bio Pond Filter | 11.8" Width 39.4ft Length Biochemical Fish Tank Aquarium Filter Pad | Durable, Washable Easy to Clean Aquarium Media Cleaner | Healthy Freshwater Saltwater | Green | 1451.2

dense, very thin filter media. Clogs too rapidly for my purposes resulting in water bypassing filter media. I normally use a much thicker, less dense material that I change out about once a week. This one requires change out every 4 days or so. Probably good for polishing water but too dense for my purposes.

Works great in my trickle tower and is a great price. Would buy again.

Works like it should.
