bonjour,

well i dont think so but...

i got a carpet of eleocharis parvula,
in the past 3 month, they have always been tiny (3-4cm) but green.

i mist some CO2 for about a week now, and in the path of the spray they first turn yellow and now some become brown (death)

is it the CO2 or the water mouvement ??

~200g. (60x36x24)
10x zoomed T8 32 watts.
external CO2 reactor.
mist CO2 by a maxi-jet 1200gph + eheim spray bar.
drop cheker say CO2>20-30ppm

merci.

No, not with this plant.

But........

This plant can brown for other reasons unrelated to CO2.

Regards,
Tom Barr

I have a similar experience with E. acicularis. I think it is due to too fast water current as I can switch the spray-bar position and reverse/induce the effect.

ok thanks,

I will test that first and will observe

merci.
