ME GFO

Description

We suggest a target rate of .02-.05 with some arguing lower levels are better. Please test with a reliable test kit. Gfo is typically used in a media reactor, but a media bag in the sump will work, just not as effective as water does not contact every side of the granules. Remember to change the media as needed. Use 1 cup per 60-70 gal of aquarium water. Net wt 250g.
