    I'm currently dosing my weeks worth of ferts all on Saturdays (WC day). Is Fe available throughout the week or is it gone within the first few days? Dosing both CSM+B and DTPA in liquid micro mix.

    The Proof Of The Pudding ("They" Do Say) Is In The Eating

    Hi,

    Depends... :confused:

    I suspect you are “pulsing” that may not be all that bad. :)

    The best way to judge is by the aquarium. :cool:

    I thought that Fe got locked up pretty quickly when in contact with other factors in the water? Meaning that the plants take it quick and thencan't get the rest

    I dose NPK once a week on water change day but, dose CSM+B and DTPA (4:1) on a daily basis just to make sure Fe is always available. My water has DKH of 6 and a total hardness of about 130 ppm. This has been working fine for me and since I dry dose, it's not to complicated for me.

    Well, the "total" iron level in the water column definitely persists. I can also buy reagents to specifically test for Ferric ^3+ or Ferrous ^2+ iron, if that makes any difference. Is one better then the other? Or is one not bio-available? (ferric / ferrous?)

    Worth at least mentioning in this thread that I have tested & observed that UV exposure will remove the iron residual from the water column.
