In my 44g tank there's tons of brown brushy algae... (I think thats what its called). I think I practically killed every Malaysian trumpet snail in my 50g when I completely cleaned it out so I want to take some big ones from my 44g and transfer them. So my question is, is brown brushy algae always present in the water and caused by an imbalance? Or is it transferred tank to tank? I don't want to bring any into my 50g if its transferable....
