Difference between iron citrate and ferrous gluconate to control PO4

[le fou]

Hello,

I am new to reef2reef, a lot of information! I have been reading about using Fe+ to bind PO4.

I am looking at making my own solution but cannot find Iron Citrate. I was wondering if I can use Ferric Citrate or ferrous Gluconate instead and still obtain the same result?

I was planning to use 3ml per 25 gallons of Iron Citrate (solution would be 49.7 grams in 1 liter). Would I keep the same dosage with the other compound?
-> I answer my own question! If I use Ferrous Gluconate, I need to use 4.5ml per 25 gallons (solution is 55.84 grams in 1 liter) to have the same effect than Iron citrate.

Can one make his/her own iron citrate solution by mixing trisodiumcitrate with ironsulfate heptahydrate?

Thank you,

Le fou

From what ive read, they should both reduce po4 when bacteria consume the organic portion of it.
