Interesting article on B/G algae and Redox Potential

These articles are just speculation and mostly based on reefs in the first article, and the part about "water ionization" is frigging rubbish. That's quackery marketing.

As far as lakes, ponds etc, this is for suspended BGA, there's only one main species we deal with and I've detailed the most about the issue.

None of the articles apply to planted stems however.
Redox is central to wetland soils, much less so to the water column.

Aquatic plants modify and change the Redox in both sediments and water column.
Higher levels are achieved with healthy growing plants, lower when they die or do not do so well.

There is a strong linkage between roots and sediment and redox. good growth = good O2 production = higher Redox.

So do not bother with Redox directly, not that it will solve any BGA in a planted tank anyway, but rather, good general plant growth. This is more a biological issue than a chemical one, the biology will modify the chemical state. Not the other way around.
