Chelated Iron In Aquariums - DTPA, EDTA or EDDHA

The best iron fertilizers are the chelate iron fertilizers. Chelates are the compounds that stabilize metal ions ( in this case - iron) and protect them from oxidation and precipitation. Different chelates ( EDTA, DTPA, EDDHA ) hold iron ions in different strengths at different pH levels. They also defer in their susceptibility to iron replacement by competitive ions. For example, at high concentrations, calcium or magnesium ions may replace the chelated metal ion. These chelated fertilizers also ensures that the iron is kept in ferrous state, plants absorb iron in ferrous state.
