Ive been looking at different threads about this and I want to keep a little macro in my display. I got this stuff from a seahorse tank at work. Anyone know what it is, and is it safe to try (wont take over). I used a blade to get it and it even has a nice, flat base for glueing. Also, this other algae is in there as well. I picked every little piece i could off of the nicer algae. Would you recommend i try this, or dont do it for fear of a take over?
