Help with iron tablet dosing

[Nano_Man]

Can any member help with amount of iron tablets per gallon. This due to growing native sea weeds hoping this will help growth. Thanks for any information on the subject .

Here’s Randy’s take:

My recommended DIY is:

Fergon tablets (from a drug store).

One Fergon tablet (ferrous gluconate) contains 27 mg of iron. Dissolve that in about 27 mL RO/DI (my recommendation, but other concentrations are OK, just don't dilute too much), the concentration is about 27 mg/27 ml ~ 1 mg/mL.

I dose ~1 mL to my tank with a volume of about 300 gallons once or twice a week.
