Which Iron

[LukeA]

Hey guys just wondering which of the following irons would be safe in my tank (http://www.masa.asn.au/phpBB3/viewtopic.php?f=148&t=203993)
Here's the list from a local chemical shop
IRON (11) CHLORIDE Tetrahydrate Tech
IRON (11) DI-IRON (111) OXIDE
IRON (11) ORTHOPHOSPHATE (Blue)
IRON (11) SULPHATE AR
IRON (11) SULPHATE Heptahydrate AR
IRON (11) SULPHATE Heptahydrate Tech
IRON (11) SULPHIDE Lump
IRON (11) SULPHATE Heptahydrate Tech
IRON (11) SULPHATE Monohydrate Tech
IRON (111) CHLORIDE 42% Solution
IRON (111) CHLORIDE 60% Solution
IRON (111) CHLORIDE Anhydrous Tech
IRON (111) CHLORIDE Hexahydrate Tech
IRON (111) NITRATE Nonahydrate Tech
IRON (111) ORTHOPHOSPHATE (Yellow)
IRON (111) OXIDE YELLOW
IRON (111) OXIDE BLACK
IRON (111) OXIDE RED (Haematite)
IRON (111) SULPHATE Pure
Iron Ammonium Salts - See Ammonium Ferro/Ferric
IRON CHELATE (Black) 12.6% Fe
IRON FILINGS (1-3mm Shavings)
IRON POWDER (Reduced)
IRON SULPHIDE Pyrites

i was using red sea but using too much 30ml a day to keep it at 0.5 so a $25 bottle was lasting 2 weeks

Mix has to be safe thanks

or if i use something like this http://www.yates.co.nz/products/fertilising/specialised/yates-chelated-iron/

whyy so much iorn??

IRON (11) DI-IRON (111) OXIDE is the same as GFO or rust

iorn sulfide and sulfer cloride will create Fe(OH)3

definitly not IRON (111) ORTHOPHOSPHATE

i think what you need is an iorn salt..i dont know about Iron Ammonium Salts thought anyone else?

read the bottom

This is for purposes of an iron supplement, such as for boosting macroalgae?

If so, many of these may work (the chlorides and sulfates only, preferably iron II), but I'd fairly strongly prefer a lightly chelated iron form to allow it to remain soluble, such as ferrous gluconate. The chlorides and sulfates will very quickly become hydroxides then oxides and precipitate from solution.

iron not for marco but the green sps that has started to brown that link has photos of my TJ

 

[Randy Holmes-Farley]

I'm not convinced that iron has anything to do with green colors in SPS, but the same comments would apply if that is the goal.

 

[LukeA]

Ok I'll let u's know if i see any changes in the next couple of week heres one from the 24-2-12

I'll post another photo in two weeks time thanks

 

[Randy Holmes-Farley]

OK, good.

Don't change anything else so we can be sure any change is from the iron.

looking at using the Yates Chelated Iron on the side of the box it says 12% iron sulfate- EDTA (should i worry about it having EDTA in it?)

 

[Randy Holmes-Farley]

EDTA iron is also not my favorite as it is chelated very tightly, but it can work as UV breaks down the EDTA and releases the iron to make it bioavailable.
