From quenton's calc thread.
FertFriend is functionally correct.
I have to brush up on php for work, so put together a calc to verify. I used this page's percent solution equivalents to veify conversion from percent solution to g/100mL:
http://antoine.frostburg.edu/chem/senese/101/solutions/faq/dilute-percent-to-ppm.shtml
and
http://homepages.gac.edu/~cellab/appds/appd-a.html
(first two on a google search)
This also coincides with Steve Pituch's mysterious *10 constant in the solution formula on his computations page.
% solution = grams/100mL
TMG is .07%Fe = .070g Fe/100mL = .7mg Fe/mL
.7mg Fe/mL * 38mL dose / (55gal * 3.785L/gal) = .128mg/L Fe
Here's my online calc. It rounds to three sig figs:

Please correct me. If anyone wants my php code just ask.

Laith said:For 55g of water volume, the calculator indicates 38ml of TMG per week (or 33ml without the EI option ticked) to aim for a target level of 0.5mg/l of Fe...
The TMG calculators I've seen online (for example: http://www.fishfriend.com/fertfriend.html) indicate that 38ml of TMG will add 0.133mg/l of Fe (and 33ml will add 0.115). Is that calculation wrong?
