What kind of macro is this?

[mightytexn]

The LFS has macro algae for sale that looks like pieces of green tissue paper. I have never seen this kind of algae in anyones tank before and was wondering what it was and if it does as good of a job as chaeto.

sounds like lettuce algae to me...

search Ulva -- see if this is it
Ulva or sea lettuce is not only good at filtering nitrates from your tank, it is an excellent food source for tangs and other herbivorous fish
