I have 220g of total water in my system and it's a little over a year old. I have about 15 sps frags and coralline completely covers the rocks. My 3 main readings are Ca:459ppm - Alk:7.7dKH - Mag:1425pm. I only dose 100ml alkalinity at this point because my calcium never changes. Is this normal that I'm dosing this much alk and calcium is unchanged? Should I dose more alk to increase it? What is ideal if I plan to maintain it SPS dominant?
