It appears that the reason why the calcium jug ran dry is because the pump got turned on full time. So it drained what was left in the jug. That would explain why calcium is so high. There wasn't that much left so that is why it wasn't a disaster.
not sure how this happened, but just realized my salinity is down to 1.020. I suspect this is why my Euphyllia have shrunken and maybe my Ricordea mushroom as well. Any suggestions on how to bring it up and how quickly? I would think possibly making a batch of pretty concentrated saltwater and using it to start topping off? Any suggestions are appreciated.
