Ive been reading up a little bit on Fe dosing and found that people seem to think that the gluconate form of Fe in Seachems Iron can precipitate out very easily and would render it useless to plants. If this is true then I would like to find an alternate source of Fe. Ive read that Fe EDTA is a better form of Fe to use but I dont know of any sources to get the stuff. Are there any commercial versions avaliable or can I make a DIY mixture of the stuff?

I saw what they called "Iron Chelate" at my local hardware store. It was 32% and 68% EDTA. 9.95 for about a pound of the stuff.

They also had pond supplement, which looked a lot like Flourish. I am not sure about the exact vitamin content of it though. It was quite cheap and treated like 12,000 gallons.

I would be intersted to hear opinions.
