If you're running a reef tank with the appropriate levels of Ca
, Purple up will do nothing for you. It's just concentrated calcium etc. Coraline doesn't grow in your tank on it's own; it has to be introduced into it. Best bet is to get a piece of LR
with coraline and scrape it to get it introduced into your tank.
