Thanks for the input. Somehow I managed to over-complicate my calculations when I first did them (they weren't incorrect, I just took 60 minutes to do what I could have done in 3 minutes). Anyways, I was thinking about getting another air pump and Gatorade bottle so I could make a micros bottle. I have 3/4 of a pound of Plantex CSM+B left, so I'm going to use that.
In a separate, but equal sized bottle (same conditions as the first) I will add:
1 1/8 teaspoon Plantex CSM+B which will give me the exact same amount of iron as 60 milliliters of Flourish (1.33 PPM of Fe).
My only other question is, should I add MgSO4 (7H2O) to the micros mix as well, if so, how much of that should I add?
