That's a common complaint. A brand named Millers, some have reported contains a red dye.

The 1st time I poured in a good shot of maxicrop with iron, it also darkened the water, to where I couldn't see the fish. It did clear up after a few days.

We are not supposed to give links to other aquaponic sites....that being said...search for .....
Dr Nate Storey....for 'understanding iron in aquaponics'.
He is very knowledgeable in Aquaponics.
