    Am I off base or could my GFO be feeding my hair algae. GFO (Granular Ferrous Oxide) is iron rust. Isn't iron bad in the aquarium because it helps feed the algae?

    I am just curious.

    The rust binds phosphates which feed algae. However, if it hasnt been changed in a while, it will become saturated with the phosphates and start leaching them back into the system.

    It's vital GFO is changed out regularly. Depending on your phosphate levels, it's good for 4-6 weeks at the most.

    Also, it should be in a reactor, or in a media bag in an area of medium flow to keep the granules from sticking together and becoming ineffective.

    Thanks, I had just herd that Iron can feed algae and since I have a reactor with Iron in it I figured I would ask the question.

    True but you have to remember that it is Iron Oxide. Not the iron ion that would be floating around in solution. It is chemically a different compound.
