I think I have black hair algae or something of the sort. Whatever it is, it sure is fuzzy. It's in the newly set up 55. I used old gravel that belonged to the previous owner of the 55's equipment only to discover hair algae? too late. What eats algae? I have loaches (( And sword plants )) in there so snails are a no go for now, though I am debating on giving the loaches away. Thoughts?
