This Filter Pad is excellent. It makes my fresh water aquarium crystal clear. I highly recommend this product if you want clear and clean aquarium. Thanks!

Good filter and does the job well compared to normal cotton, sinthetic ones. Washable too, saves money and lasts twice the normal simple sponges

Product is as it is described and shown in pictures and works better than other filters

Does the job well

Good product, can be cut and used as required.
