numb, dont try to fix the fuge problem with a bottle of magic potion. If algae wont live in the fuge, then adding iron wont fix that problem. It will only accellerate growth.
But like said before, the only thing we need to add to our water is salt and calcium. Do water changes regularly and all should fall into place...
P.S. NICO, what are the "tips of your micros"?
