Are these roots or algae?
Six weeks ago I added some additional plants to my 29 gallon tank, and with them came some staghorn algae which I've never had in the past ....so it raises the possibility of other algae coming in as well. I also added CO2 on a regulator and have been giving more fert than in the past - so the potential for increased growth of plants/algae.
So here is the question ...I've had a "crypt forest" on the right side of my tank for years. Over the past few weeks I have noticed this growth at the base of the crypts. They look like roots ...but I am worried it may be some kind of algae I've never seen before. I have noticed these "roots" before.
Hopefully you all can see the image attachment - first time doing this. Any ideas? I also attached a pic of the tank ..crypts are on the far right.
