My success with GFO has been marginal. Although it's not necessarily all the GFO's fault. Usually I have the greatest of intentions of swapping it out regularly, and keeping it up for 6-10 months religiously. Ya right. I'm good for the initial getting it set up, then usually 2-3 months down the road I remember and think I should change it, and probably another month goes by because I rationalize that I just got it going a month ago, it should be good for a little while longer.
So needless to say I can't say I've ever even had a noticeable change in my tank. Somehow I've gotten pink cotton candy algae in my tank and if left alone it gets to plague proportions. I may have to give Foz down a try.
