So MarcoRocks now sells aquacultured live rock to use to seed the base rock you buy from them. Does anyone have experience with this specific rock? Aquacultured Live Rock ( seed rock ) - MarcoRocks.com Store I know that I could get a piece of rock from local reefers to accomplish the same thing, but after fighting bubble algae, Valonia and Bryopsis I just don't want to gamble with introducing that into my new tank. In theory this rock shouldn't have those issues. Thanks.
