hi, i am having problem with growing cabomba carolina . i put them in my tank around 2 weeks ago , before that they were in my out door pot . their tops turned brownish white but grew with a steady rate . but now they have suddenly stopped growing . their tops have turned completely white . this has happened to me before but i did not have any substrate at that so i suspected that no substrate was the reason . i know they will soon start breaking off.
details
substrate : thin layer of black soil , 3 inch layer of sand
light: 20W X 2 CFL(cool daylight) 15W X1 CFL (warm sunlight)
fishes 7 guppys 1 betta 3 mollys and lots of wild shrimps . what is its reason and how can i prevent it |

Maybe there is not enough co2 in the tank..also lack of nutrients can cause the leaves to lose their coloration.
Do you supply co2??

All plants need time to acclimate in a new tank.
I would keep an eye out for new shoots and leaves.
If they are not sprouting, then start to worry.
Cabomba has grown well in my tank most of the time.
But time to time a few shoots melt after being trimmed.
Just a thought.
Thanks,
Arin |

There is no co2 supply . co2 from fishes only.
Arin they grew well for the first week but have now suddenly stopped growing.
The tank' 18 gallons . it contains 15-16 gallons of water
Hard water? Have no idea .
As i have already mentioned they grow very well in the outside pot of 15 gallons
Thxxxxx
Vishu |

They grow very well outside because they receive enough sunlight..
they grew well for the first week because they had enough nutrients stored in them..now since they have used up all the nutrients..i guess they are lacking nutrients...the lighting seems fine to me though.
try introducing DIY CO2.

Vishu,
There are three pigments in plants which gives it the coloration 1. chlorophyll 2. carotenoides 3. Anthocyanins
the chlorophyll gives the green coloration the carotenoides gives the yellow coloration and anthocyanins gives the reds and the purple coloration. Now the characteristic of chlorophyll is that it is very unstable and it breaks up easily under high lighting and the plant needs the nutrients and Co2 to build it back but if does not happen the carotenoides are exposed thats why you see the yellow coloration this is called cholorosis. Even at this time sufficient nutrients are not given then the carotenoides also breaks up. Thats why you saw the white coloration. If care is not taken at this point the plants start to disintegrate this is what is called as necrosis.
Cause for your problem
you have about 3.5 watts of lighting in your aquarium which is on the bit higher for a non Co2 aquarium. In a planted aquarium growth is driven by 3 factors 1.Lighting 2.Co2 3.Ferts. And for success all three should be in balance.
Since your aquarium does not have pressurized Co2 system my advice would be to reduce the lighting to around 50Watts your current total adds upto 65 Watts
Secondly if possible change the light spectrum 6500 kelvin. I remember one of your light had a warm white rating which is around 4500 K and emits a spectrum which does not overlap too much with the photosynthetic spectrum
also make sure that you supplement this with sufficient nutrients. |

Vishnu,
As you are not having any CO2 support at the moment, please start the DIY CO2 or start giving Glut Dosing.
Without CO2 the plants will not thrive. |
