ive heard that seachems products are better...but i usually take that with a grain of salt. one person i talked to was super passionate about using flourish iron over the brightwell iron product. something about how the form that the iron is in...the plants have a harder time using the iron in the brightwell product. its over my head, so instead of trying to understand it i took the lazy approach and just bought the flourish iron.

I have used one bottle of the brightwell Fe. It didn't seem to make any difference in the plants as compared to Seachem. Perhaps a longer experiment is necessary. I just got another bottle. :D

Seachem's Flourish Iron is composed only of iron gluconate which is shown to be readily absorbed and used by plants. Brightwell's product also contains iron EDTA, which is less available to plants in an alkaline environment.

so if my ph is acidic is there a difference or is alkalinity different than what I'm thinking?
The EDTA form of the iron takes longer to be used up so it provides a more stable supply of iron or at least that's Brightwell's philosophy from what I read on their website. The ferrous gluconate is absorbed by the plants very readily.

Yes, an acidic pH would be best to see the benefits of using the Brightwell product.

Thanks Aaron. I was looking on the bottle to see what kind of iron it was (since the FE uptake lecture :D). Since our planted tanks are usually low pH, I wonder if it would make a difference. It's about the time for me to buy a new bottle. :D
