This is the coarse grade in a 25 lb bag. Maytronics puts the glass through an activation process that changes its surface, and that treatment is what separates it from plain crushed glass.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFiner, cleaner filtration\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe activated surface has about 300 times the surface area of sand, which lets the bed trap particles down to 4 to 5 microns instead of the much larger particles sand catches. The surface also carries a negative charge, so it attracts and holds bacteria rather than letting them pass, and it is self sterilizing, which inhibits bacteria and algae from reproducing inside the filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLoading it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDrain and empty the old sand, then load Activate to the media capacity listed for your filter.
