Activate is a glass filter media that replaces traditional silica sand and is designed to provide you with clearer, cleaner, healthier water. Our proven activation process makes this product scientifically better than all other filter media and far superior to sand media.



- Ultrafine filtration for cleaner water. Creates 300 times more surface area for superior filtration down to 4-5 microns.

- Negatively charged filter media for cleaner water. Attracts and captures harmful bacteria like a magnet.

- Self-sterilizing surface for healthier water. Prevents the growth of bacteria and algae by inhibiting reproduction.



ACTIVATE comes in two different grades - Coarse Grade 2 and Fine Grade 1. Coarse goes on the bottom of the filter and Activate Fine is used over the top as a top layer. Once Activate is installed, back-wash the filter 3 times prior to use. Activate is provided in a sealed bag and ready for use. Follow the sand filter manufacturer's instructions for filling the filter with sand and follow the steps below to determine the right amount of Dr. Dryden’s Activate for your filter.
