I'm trying EDDHA Fe in my tank to see if it changes anything for the plants. I was under the impression that below 0.2ppm it would create a slightly noticeable taint in water.
Using butterfly calculator, for my 300L tank and a 0.1ppm weekly dose, it says I should dose 0.5g.
But this amount makes my water super dark, it looks like a blackwater tank. It is actually an interesting look, but not what I had in mind.
Is this what is supposed to happen at this concentration, were my expectations unfounded? Or maybe there is something wrong with the calculator or maybe my Fe supplement?
