Take it easy with the garlic XTreme - open the bottle and take whif ... it is strong stuff :o

Take a pinch of flakes and put them in a small amount (tbs) of water from your tank and add 2-3 drops of Garlic. Let 'em sit for 30mins and dump flakes water & all into the tank. I also do this with Brine and Mysis shrimp

Don't know if the Ogo would absorb enough to make a difference? You can definately try - same method as for the flakes I would think???
