Hi all,

Recently i just set up my 8 footer planted tank. water should be stable but somehow my plant starts growing black spots on them. Anyone knows whats the reason?

I am running on a 6 feet T5 lighting, over flow sump tank. No soil and sand. No chiller. Co2 4 bubbles per sec. Any experts any advise?

You need to take some macro shots of the black stuff for us to see.

This is how the black spots looks like..

My ferns are also turning black.......

what is your tank temperature?

[blue33]

You might be missing CO2(not enough), fertilizer, lighting etc... Without fertilizer, your CO2 is useless.

i am having nana in my tank and they are turning black too.. i know nana and fern does not require strong lightings. My water temp is 29, i thk might be lack of nutrients..

Long tanks are hard toplant and to make them look good. the black is some kind of infection I don't know how to curl it .it may be a fungus

[turbo51]

Fungus.. or is the water temperature too high? What kind of chiller can i use?

Any experts here know??

[thebaldingaquarist]

for the leaves that have this problem, does the whole leave slowly die off? does the spots eventually become holes?

Does the black spots occur on the stems or branches? which leaves are affected? old leaves? new ones?
the leaves are close to the light source?

what algae do you have (if any)?
what algae crew do you have?

My 2 cents.

1) Lack of water circulation in the tank as the tank is too large.
What filteration did you use?

2) High temperature - Can use 3 fans.
Chiller not required as your plants are the low maintenance type.

3) Inconsistent / long lighting duration

4) Tank not cycle properly before adding plants

5) Inconsistent fertiliser regime. (Not require as as your plants are the low maintenance type.)
