Aqua One Aquis Advance 2pk Sponge Pad
For Aquis Advance 550/750 401s
Genuine and original Aqua One sponge filter pads are designed to trap and remove larger particles of aquarium debris as it passes through the trickle filter system. Whilst the sponge can be rinsed in aquarium water and reused but should be replaced when the cell structure starts to deteriorate.
