Hidden toxins in tank water...again...?

Hi all,

Regarding my previous thread Hidden toxins in tank water..?, I have a further question:

I was at the LFS looking at plants today, and I realized something: plants release "byproducts" too... Everyone is always worried about fish waste building up between water changes, but what about plant waste...?

Are there not "plant byproducts" that could build up?

By products; all they release is O2 and CO2. I mean dead plant matter will of course realease N, but what toxins are you referring to? I know that Egeria densa releases antibiotics in the water; which it releases to kill of cyanobacteria (BGA).

Photosynthetic metabolism itself does not release any harmful byproducts that I know of.

Specific algae/plants produce toxins as a defensive mechanism. Raul gave one example. Here's a few things you can Google for some interesting results: toxic BGA, red tide, psoralens, Caulerpa.

Ok well what I was thinking was that some plants dont like other plants. For instance - I know that Daffodils will kill Tulips if you plant them near each other in your garden. And I have heard of people having similar reactions in their planted tanks, but I cannot remember the circumstances. I remember the word for it was "allatrophic" or something like that - but I couldn't get the spelling close enough to search for it here in the forum.

This was only a question of curiosity. I wasn't trying to troubleshoot a problem in my tank - if the water was old enough to make something like this happen, I think the fish would be dead... :-)

Thanks.

Allelopathy is the word you're looking for. Fairly well understood in terrestrial plants, not well understood or proven in aquatic plants.

Curiousity is a good thing.
