Hi,
I have just done a 90% water change in my 800L tank with natural sea water.
After 24 hours I have just tested the Alk and calcium levels. The calcium is reading 320ppm.
How normal or abnormal is this? One of the big reasons behind this big water change was to increase the calcium levels to get a good starting point to buy corals.
