I have a question about Iron removal from water.
As you can see from the water analysis , soluable Fe is 0,05 ppm and Total Fe is 70 ppm.
Is it possibble to reduce the total Fe amount to <0,2 ppm only by using sand filter?
I think there is no need to use greensand , aquamandix or other minerals that oxidize the iron , since its already in oxidezed/precipitad form?
Thanks in advance:)
