Seems like the cheapest way to get macros is to get them from people who already have them. I'm looking for any macros really, specifcally halimeda at the moment. Just post pics, and I'll pm you if I'm interested. I also have red sea grapes and birdsnest gracillaria available for trade.
Just got home and noticed something growing on my halimeda. Kind of looks like broccoli or some type of eggs. Also it turned a weird yellow color and bleached a little bit.
