I am trying to make my own Fe supplement using Randy's guide found here:
http://www.advancedaquarist.com/2002/8/chemistry
Where Randy says:
"I selected a dose of about 0.1 to 0.3 mL of a solution containing 5 g of iron (as 25 g of ferrous sulfate heptahydrate) in 250 mL of water containing 50.7 g of sodium citrate dihydrate. This liquid is dosed 2-3 times per week to my system with a total water volume of about 250 gallons."
1) Can I use Ferric Chloride instead of Ferric Sulfate? I can see no reason why not, but wanted to double check.
2) Can I use magnesium citrate instead of sodium citrate (this substitute I am a bit more suspicious of)? If not, are there other readily available substitutes or does anyone know an easy source of Sodium Citrate? I found found some DIY recipes so can make sodium citrate if need be.
