It catches everything the water is carrying before that reaches the chemical and biological media behind it, which is what keeps a filter working rather than slowly clogging. Run coarse first and fine second: the coarse sheet takes the big debris and keeps the fine sheet from blinding within a week.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe part people get wrong\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWool is a mechanical medium and it is meant to be replaced, not preserved. It also grows a share of the tank's bacteria, so changing every sheet at once alongside a filter clean is how a mature tank ends up with a nitrite spike. Replace the wool on a different week to the biological media, and if you are changing several sheets, do half now and half in a fortnight.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSheets are meant to be cut.
