My Tank Cycle!!

Ryan, how long has your tank been cycling? If you started from scratch with uncured rock and it's been cycling for 6-8 wks I think you're OK. You might want to test a few different days to make sure but if it's been a while I think you're all set. Just start off adding fish slow and give the tank some time to adjust to the added bio load. Like some others have mentioned don't worry too much about the Mg now, concentrate on the Alk and pH (which IMO 7.9-8.3 is OK, it will fluctuate) until you're ready to add corals. good luck.
