HOW TO REMOVE IRON FROM YOUR FISH PONDS WATER

May 31, 2011· to most freshwater fish-keeping (.5 is lethal). Iron-bearing water, when fresh out of the ground, is usually clear because iron is in the soluble ferrous iron form. As soon as it reacts with a little oxygen (.14 ppm per part of iron), the iron is changed to the ferric state and turns brown or orange.
