what do you guys know about mangrove plants helping out with hair algae? its seems that i have a real bad problem with this and so far the best thing ive seen to clean this is the plant. if this is a helpful plant to get then does anyone know where i can get some and about how many i would need for a 55g with about 60lbs of LR? it seems to be covering only one rock but that one rock is completly covered in it.
