I noticed that there is this purple algae that has taken over my tank. It started out as just on the glass and I figured between me scraping it off and my plecos and snails it would get taken care of or at least be controlled. I was wrong it is now covering a lot of the substrate. I don’t have much experience with algae and whenever I look it up nothing matches the description of what I have. I was wondering what type it is and is it harmful to my fish? Will my snails and plecos eat it? My tank is next to a window so I’m not surprised algae grew. I will be attaching a picture.
