Hallo Randy....I'm Yandy from Indonesia. Thanks so much for your articles that help me so much...
In your article Iron in a Reef Tank, you make iron supplement from ferrous sulfate heptahydrate and sodium citrate dihydrate.
But the problem is, I don't have that ingredients. What i have is
ferric chloride and EDTA, can I use them? How?
Thanks...
