What the problem with this plant ?

[csk]

Hi ! i having this plant (dont know the name see picture), i noticed when it's grow upto certain height around 6" from gravel, the leaf on top turned facing south and rot away, what is the problem ? any idea ?
Some glosso leaf looks dirty, like something coated but some other new growth leaf look bright green, can anyone advice me ? Thank you.

Tank size : 120cmW x 30cmD x 45cmH
Co2 - 3-4 bps with external reactor,
fan cool, 26 - 28c
2217 eheim biological filter
Night time turned on air pump for 10 hours,
KNO3, K2SO4, MGSO4, Trace Mix - daily dosing
gravel base with fert.
T5 - 54 watts x 2 on for 10 hours daily
weekly 40% water change

Obvisously, it could be Hemanthius Micromanthem. Yours tank is 45cm high, perhaps there is not enough proper light near substrate.

Black Brush Algae sticks on yours glosso.

Hi,

I think Peter is right, what you are seeing is red algae, BBA.

I was hoping Tom Barr would get here first, but all together, it is CO[SUB]2[/SUB].:excitement:

I see this every year in my non air-conditioned areas as the temperature rises, particularly when it rises suddenly.

Though the trigger is temperature, the CO[SUB]2[/SUB] cannot seem to keep up with the increased growth the higher temperatures bring.

Gently, slowly increase the CO[SUB]2[/SUB]. You will be fine.

hi Biolante
This may depend on the plants,
things like Hemanthhius Micromanthem don´t need any additional Co2, because the plant did not have much Co2 demand.
This is Hemanthius grown in a small 5L techless tank without any water pump circulation and no additional Co2 (drop checker would show blue color):

This is Hemanthius grown with "standart setup", water circulation and certainly additional Co2:

Yes, there are differences in the grow how the plant will do with or without proper Co2,
but if leaf Internodes get any "long" - it´s most likely that some other things are going wrong, too.

As for Red algae, increasing Co2 and working on flow may help a little bit -or- using Excel to get ridd off it.

Temperature, Q10, So Forth Are The Answers to the Obvious Questions

Hi Peter,

I view the red algae as a symptom of inconsistent CO[SUB]2[/SUB] without regard to whether the plant, rock, glass or driftwood requires additional CO[SUB]2[/SUB].

The inconsistent delivery of CO[SUB]2[/SUB] is independent of delivery method. I see this in tanks that have no enriched CO[SUB]2[/SUB] at all.

Once the CO[SUB]2[/SUB] stabilizes the red algae eventually tends to go away. Though the residual and collateral damage remains. In most cases, most plants cannot repair the damage, red algae’s holdfasts, indeed holdfast even in death.

As far as Excel is concerned, it has about the same value as increasing or stabilizing the CO[SUB]2[/SUB].

As a biocide/algaecide Excel is not particularly effective against red algae, particularly the flatter, more tar like species.

Oxidizers such as Hydrogen peroxide or bleach are far more effective.
