It's cyanobacteria aka blue-green algae if it is. Ugh...get it all cleaned out as much as you can and get your nitrates down. Add some really quickly growing plants if you can to eat up the excess nutrients in the tank. This stuff gets outta control pretty quick.

No, that is not the algae I have, What I have starts out as a white looking hair, then it turns black, It seems to concentrate on the edges of the leaves, but is also in the lift tubes of the filters also

i also have that sort of algae, all mhy fish seem to be nibbling at it though. i regularly clean the tank and ornaments but cannot get rid of it completely, i have increased water changes whcih does seem to be keeping it at bay. if this flourish excel stuff is used will the problem go away completely? is it worth risking the fish

I've seen this too, I can't answer your flourish question because I have never done it myself.

that appears to be what I have. but much more extensive, It is mostly on the edges of my plants and also on the lift tubes of my filters. I will try to get some pics and post them

This is exactly what I had. Excel 2x dosage for three days and after a week, it was all brown, and another week (with a water change), it was gone. I have a lot of Otos, a Pleco, Hillstream Loach, so they may have helped. But once it turns brown, you know you won.

It is not really black (I think), it is just very dark green.

isnt that BBA? I have it in my tank too. I read that a CO2 injection and more water movement helps. Also, for me, my peppered corys started to munch on the stuff recently and it seems to be keeping it in check.

I hear bristlenose plecos, american flagfish are good choices as well for this. Unfortunately, the only BN I could find were albino and no AFFs, so I tried Excel and I only wish I got it earlier.
