The water should flow through the open or looser fiber side of our premium pad first. This will allow the larger debris to be trapped before entering the tight weaved lower section of the pad.

Your aquarium water should flow first through the FilterFirst pad to remove small to large particles from the water, then through the polishing pad to remove fine particles. This layering method will increase the useful life of your polishing pad.

Most hobbyists rinse the filter pad every two weeks and replace them monthly during a water change. The more often you change filter pads the better your water quality; filter pads remove organic solids before they have a chance to further break down.

No, you do not need to remove our Premium filter pad when medicating your fish. Our filter pad does not remove any medication or other chemicals from the water. The pad only traps debris floating in the water.
