Filled my tank last week. Haven't had time to bring salinity up to par. I actually forgot to check salinity and threw in some coral stuck on my shelf rock. All dead now. Either from .18 salinity or from me forgetting to wash my hands after putting a bunch of Vicks vapor rub . by the time I realized I had it on my hands I was already in the tank for half an hour doing rockscape. I know hypo is OK to a certain point. But is .18 way too low? I Dont want my coraline bleaching.
