Aqua One Wool Pad - MariSys 240 3/pk 411w

A 411w pack of two new Aqua One Polymer Wool pads to fit the top basket of the Aqua One Marisys 240 and Aqua One Marisys Pro under tank marine filtration systems. Polymer Wool makes superb fine filtration material for aquarium use as it is capable of trapping even the finest particles. Aqua One Polymer wool inserts are safe for use in aquariums types including fresh and salt water environments. It cannot be reliably rinsed clean and should be replaced once per four to six weeks when your filter is cleaned out. Blocked Polymer wool will greatly reduce your filtation capacity putting your fishes lives at risk so do change as often as required.
