How to mix Granular Activate Carbon and Granular Ferric Oxide

Made a little instructional video:

Weigh out the GAC and GFO using a digital scale. Mix outside or in a well ventilated area and wear a mask to avoid the harmful dust of the carbon and iron oxide. Once weighed and bagged wash and soak in RO/DI water.

Disclaimer: It is not recommended to mix GAC and GFO. They aren't as effective mixed and have different useful lifespans.
