Don't use it. That's Fe-EDTA, which is not appropriate for aquaponics for a number of reasons<br />
1) FeEDTA is only usable with pH levels below 6.5 ish.<br />
2) FeEDTA prefers calcium to iron, so it will often drop the iron as precipitate and bind the calcium.<br />
<br />
Look at Fe-DTPA or Fe-EDDHA
