Product details

Activate is a glass filter media from Maytronics that takes the place of silica sand in a sand filter. 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.

Finer, cleaner filtration

The 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.

Loading it

Drain and empty the old sand, then load Activate to the media capacity listed for your filter. This bag is the coarse grade; the fine grade is sold separately.

Questions and answers

What people ask about this product, answered by our pool techs.

Can I use this in my existing sand filter?
Yes. Activate is made to replace silica sand in a standard sand filter. Empty the old sand, load the glass and run the filter as before.
How fine does it filter?
Down to 4 to 5 microns, according to Maytronics, thanks to an activation process that gives the glass around 300 times the surface area of sand.
Coarse or fine, which do I need?
This is the coarse grade. The fine grade is sold separately. Follow the instructions for your filter size on how much of each to load.
How many bags do I need?
Each bag is 25 lbs. Check the media capacity listed for your filter and buy enough bags to reach it.
