hornwort and algae
>The following was quoted from the www.tropica.com website:
"Ceratophyllum demersum often forms monospecific populations
and is found down to 10 m depth as individual very slow-growing
plants. In the aquarium, on the other hand, it prefers relatively high
light, and it does not tolerate transportation for extended periods. It
excretes substances toxic to algae (allelopathic behaviour) and at
good growth conditions it efficiently inhibits most algae growth. "
Does anyone know is this is really true? Does anyone have any
experience with this?
My only experience with hornwort was in a 29 gallon tank, sitting in a
south window. No CO2, no filter. MAJOR algae. Thick pale green
cotton-y stuff that coated everything, hornwort included. That
particular algae is a problem in any tank I have ever set in direct
morning sunlight. Maybe hornwort stops other algeas, though, since the
fluffy stuff was the only kind I had a problem with. But thinking about
it, maybe CO2 would help fix that problem...
Ok, here goes another experiment!
