I'm struggling to understand the benefits of different iron chelators, specifically EDTA and DTPA; also the benefits of certain ferric salts, including iron ascorbate, iron citrate, and iron gluconate.
I am using EDTA EI trace fertilizers daily, hard tap water, and EI macros.
I am also using Seachem Iron (Fe ascorbate) immediately after weekly water changes. Mainly because it seems logical before chelator and phosphate levels rise due to EI.
I had a look back across some of the old threads and I feel rather lost. It would be nice to have some sort of idea of what does what because I have a dutch hybrid where I am looking to reduce nitrogen and raise iron levels - probably. I'm not sure this is the best approach - but I just need to understand these fertilizers so that I have the knowledge to deliver iron in the most effective way.
Many thanks -
