Feel free to click pictures a couple of times to enlarge them.

Is this algae, and if so, what kind is it?


Also, is this green spot algae? Top part is same stuff as first photo.


Thanks!!

The bottom black square is green spot algae. Anubias are common to get it due to their slow growing nature. I'm not certain but I think potassium increase helps.

Oh, so the plant in the bottom picture is an Anubias?

I might try increasing Potassium on my next fert. mixture

Really the Anubias commonly get that due to age. Like was said before the leaves just last longer cause they grow slower than most plants. Java Fern have that problem also.
The other kind I don't know the name of but is what has been mistaken for hair algae.
You should have the light(s) on for less time each day as that is what makes this kind grow. I have mineon for 6.75 hrs per day reduced from 7.5 hrs to try to get that kind
a bit less than I had it before. I like that kind(both really) and keep high light in my tank to make it grow for me. I just don't want it to take over. So now I'm learning to "control" it so I can have just as much as I want but not more of it.
Knowing what kind and how much light you have would make it easier to suggest
how much to reduce it to. Also how far it is from the top of the water to the bottom of the tank(top of gravel) would help.

I'm not 100% sure but the tuft on the top picture looks like cladaforia (sp).

I have a thread in the Fertilizer section but it wasn't getting many responses on the algae part, so I asked in here. I think that thread has all of my tank stats for the most part.

Should I raise my potassium to help the green spot, or not really?

How heavily is your tank planted?

How heavily is your tank planted?

I would say it is medium to heavy....There is no real room to fit more in too much.

Like I said, I have a thread in the Fert section that should show some more pictures.
