Preiously, there was a monti pokerstar, an acro, a stylophora and the chalice (which was like 6" below) and now, in the new location, there's magician paly, a green zoa and a monti confusia (or something like that; I can't remember the exact name).

I was thinking its either because of the chalice or because of the low alk. Is it possible to have STN due to low alk?
