Generally it's chelated(ETDA etc), so I'd not use it for the water column.

Hi Tom,

What would you use to increase iron instead of FeSO4? I bought some, which is apparently not chelated, and a quarter of a teaspoon was enough to turn my tank into milk :-/

Thanks,
Naythan.

I thought I better add a bit more info, not sure if it is needed, but I notice most people do :)

80 gallon, CO2 (40ppm), using EI, with trace, 220W T5 lighting, GH6, KH8

Non of my plants that should have been showing some red, were;

Eusteralis stellata
Limnophilla aromatica
Ludwigia inclinata

I doubled the amount of trace for a few days, some slight pinkness, doubled it again, new reddish leaves and stems. A few days later, cloudy water.

Anyway, I have quite a few shrimp and I was worried about increasing copper levels etc by using more trace, so looked for straight iron solutions.

I hope that isn't too much info, or stealing the thread, my question remains, what is the best solution for dosing iron at higher levels, hopefully with out turning the tank to milk.

I was looking at Flourish Iron, but that of course has a considerable price tag on it, compared to the trace mix or FeSO4.

Thanks in advance and sorry if my first post is a bit rambling.
Naythan.

Most of the traces made use SO4's. They dissolve them in solution and add a chelator. They use the SO4 metals to dose to farm fields etc.
They do not need the Chelators.
Chelators allow more dose to be delivered to the leaves.
So you do not need to add nearly as much.

You should never get milky water from dosing traces.
