I have a fairly new tank, no pest due to the dry rock I have used. But it also looks very sterile. I would like to seed it with some pink-ish coralline. I know there the coralline-in-the-bottle solutions out there but reviews are very mixed and shipping temperatures could kill it all before I get it. Also I am a bit skeptical about those products to start with! Does anyone have any clean scraping to spare? I am in the Brentwood area.
