Looking for pointers

Your lighting, flow, and w/c schedule seem fine. We can worry about those later.

What salt are you using? Are you using RODI?

Deep sand bed is so 2001. I'd lose that.

API kit is fine for ammonia, but I would replace the following; Salifert for Alk, Calcium, Magnesium, Nitrate, and Phosphate. Down the road, get a Hanna Phosphorus checker for more accurate reading. 1 - 2.5 is awful for po4. Don't worry about pH, that will take care of itself.... and throw the Nitrite kit in the trash.

SPS are very demanding and require stability, stability, and more stability.

Also get a good refractometer ($70) and mix your next w/c at 1.025. You should see better parameters.

Some people might argue the point, but Alk at 11 is way too high for my liking. I would aim for 8ish.
