Bob, do you have any recommendations for the most effective GFO to purchase? Dos and don'ts? I recently purchased a small amount of granular ferric oxide from BRS to help combate a small algae problem I am having with little success.
I know your first recommendation will be to purchase a good PO4 test kit, which I haven't yet, but is there a way to know when the GFO is exhausted with out testing?
My first batch I ran for 3 weeks and changed, this second batch is due to be changed after next weeks water change. Not even sure if this is a good idea, but I figure it's better than leaving it in for longer and having it leach into the tank.
