what is this?
I first saw this stringy stuff that you see attached to the leaf in one of my planted jars. Easy enough to remove there... it was on a few small rocks. I removed them. Now I see it growing rather thickly in one corner of my 10g. It's on my cryptocoryne undulata, on the rock behind it, and on my marsilea minuta. What is it and how do I get rid of it?
The 10g does get some indirect light from a window in the morning. I'm now covering it with a blanket in the morning so that is stopped. I don't turn the light on in the tank until mid afternoon. It remains on until late evening, so it gets about 7 hours of light with a daylight CFL. I don't do cO2 and the only livestock in the tank at the moment are snails.
Water params last week during my last testing were:
Plants and snails are doing well.
