Algae attacking growth tips?
So I don't have a camera capable of taking a decent picture, but I'll try to describe the algae I'm seeing as best I can.

It's only occurring in my rotalas after I trimmed them and replanted the tops. If this is what the growth tip looks like, \ / , the algae is a dark green spot nestled right where new leaves should be coming from. Looks like this \o/, where the o is a little spot of algae. It's only right at the growth tip, on none of the older leaves.

Anybody have an idea what this could be and how I can treat it?

Drew up a little picture to better show what I'm talking about. A dark green ball of algae right where new leaves sprout from.

I have had BGA aka cyano do that to Rotala tips. Not sure why it happened or why it stopped happening either. Big help I am.

Well thank you for giving me an idea of what it could be. It's also good to know that it went away on its own in your situation. I'll probably ride it out and see what happens... I just hope it doesn't kill the stems because I replanted the tops and didn't save any of the bottoms :/

EM will kill it, so will a black out, so will manually, but with a lot of labor, removing and harassing it for a few days, water changes, good general care etc.

When I forgot to dose a few times, I got this, annoying. After a few weeks, got rid of it manually.
