What is this black stuff on some of my plant leaves? How do I get rid of it? Is it a type of algae or is it diatoms?

Curious because I've had the same thing.

I just noticed it a couple weeks ago. I thought it would go away but it hasn't.

I have the same problem, my cold water tank gets it but my 4 tropical don't.

I don't know if something is lacking in my tank or the leaves are just dying.

I have done some research and I think it is some type of algae.

It looks like bba hard to tell from the pictures though. What are your tank specs. I had the same problem while fine tuning my co2.

Okay. Do you know of any fish that would eat it? My Panda Garra aren't.

What your photoperiod,what kind of light do you have and do you use co2?

What your photoperiod,what kind of light do you have and do you use co2?

I have T5HO lighting that is 78 watts in total (2 bulbs). I run the light for about 9 hours. I use Natural Aquarium Vital 2-3 times a week for my CO2, but I don't think it helps any. Here were my readings:

Ammonia: 0
Nitrate: 2.5
pH: 7.2 (I am lowering it to about 6.6 or 6.8 at the moment)
Nitrite: 0
