Trace Toxicity = Plant Enzyme inhibition?

Hello everyone.

I'd like to open a new thread about the effects of traces toxicity after having discussed it a lot on the thread below:

And again about possible BBA causes on a different forum:

What exactly causes BBA? Part 2 - Bacterial imbalance | Page 17 | UK Aquatic Plant Society

After discussing and testing myself that by reducing traces (specifically CSM+B) in EI dosing regime results in high benefits for plants such as increased growth, overall health improvement and, mostly evident, better defense against algae (BBA), I've come to the conclusion that toxicity may simply inhibit plant enzyme production in some way. That's explained in several papers and studies around the web, here is an abstract example:

Effects of metals on enzyme activity in plants - ASSCHE - 1990 - Plant, Cell & Environment - Wiley Online Library

In my own experience, that would be the only logical explanation in the observation of BBA disappearance from old leaves of Anubias in my tank after just 2 weeks of reducing traces. It is my idea that by reducing or removing toxicities, plants re-gain strength in enzymatic processes that increase their natural defense to external pathogens as well as algae, and not only prevent new algae to infest them, but they are able to "cure" themselves as I have experienced.

I'll wait for your thoughts on this possible concept which would open new ways of combating and mostly preventing BBA in our tanks.

What about PPS-PRO levels of CSM+B dosing?

Also really curious on this one, but I dont use CSM+B...

I've asked Marcel exactly the same thing in other topic so really hopping on some enlightenment ...

Best Regards, Nuno Matos

Hi fablau,

I just want to tell you that it's really interesting concept that can explain a lot of our issues, but unfortunately I don't have enough knowledge in this field to make any meaningful comment. When I have an oportunity I'll try to ask one plant physiologist I'm in contact with. If you have any biology or agriculture university near you, you'll surely find some experts who will be more than willing to help you, and explain how can elevated levels of traces affect plant metabolism or enzyme production.
