You get a pretty good amount of Fe in the Flourish you are dosing.
If you are dosing Flourish Iron as a supplement it is best dosed on a daily basis for best results.
For the tank you describe, I would start with 10 - 15 mls at water change and the same at mid-week. On all the other days start with 1ml./day and see how the plants respond.
Unless you have plants that need a lot of extra Fe it may not even be necessary to dose extra. I have a ton of Crypts. and found that 1ml./day made a huge difference in their color, the crispness of the leaves and stimulated growth that I hadn't seen before.
All this is assuming that you are dosing N, P and K as well for a balanced regimen. If not, the odds are you are going to have problems.
