Assuming your readings are correct I would up it to 80 and see if you can't get it up a little faster. ( I did not mean that as it sounded. Lol) your calc. is high because your alk. Is low. Your corals can't absorb calc. when your alk is below 7. Time to move things along a little faster before your sps
Remember as you add SPS
and as they grow the demand will increase in your tank. You should have to add more then you were when you started.
LOL! I just got it. I'll kick it up to 80 tonight and check in a couple of days and yeah, I'm going to change to RC. I remember hearing that when you change salt, you need to do it slowly with a 20/80, 30/70, etc mixing of the two salts. Unless you think I can just switch.
I do have some good size colonies in there, so maybe they're drinking it up. Makes sense about the calcium not dropping cause of the low alk inhibiting the process.

I'm feeling pretty good about the results. I have an old Salifert test I was using and bought a brand new one about a month ago. Both tests give identical readings.
Fish look great, but corals, while polyp extension is good, colors are pretty dull. No tissue loss yet.
