Just my opinion, but I think your lights are set too high and the Alk/Ca are too high considering your very low nutrients.
There is a separate area on this forum that has pages upon pages of the AI Lights. Personally, I have the AI Prime HD and I will attach my settings.
Everything I read is you should really only peak your lights 3-4 hours a day. I don't know if the respiration intervals do anything, but most people have said extensive peak lightning is not good.
Additionally, take a look at this article:

Turn your UV and V down a bit. Your more than likely burning your new additions as you ad them.
Red Sea reef Energy A/B add carbohydrates and aminos but not trace elements. Also kinda hard to believe that you have 0ppm phosphates from natural seawater, out here on the west coast natural seawater runs up to .25ppm phosphates. Gotta get them nitrates up to around 5 also.
You could also check the lfs rodi for chlorine

I bought the BRS 6 stage with an extra membrane and it works well for me. I would wait to add trace minerals til your reef shows a "need" for them and you can test for them.
I was buying natural saltwater when I started reefing and we got to .45ppm phosphates. I started mixing my own saltwater with Red Sea blue bucket and my reef looks so much better.

This is off the wall, but possible:
You may have more nitrite, nitrate and ammonia than you think.
Enough to grow softies well, but kill SPS.
During a very hot spell many years ago, I noticed my test kit reading zero when I knew damn well the tank had not had time to cycle.
I had left my test reagents in the hot van, and the heat destroyed them. I had to throw away every reagent and buy new.
You may ask your local shop to test your water, or you could simply check your tests. (Hint: a drop of urine in an ammonia test will show a positive - if not, the reagent is bad.) :spin3:
I think you nitrate and phosphate levels are too low for the given alkalinity level. Either increase P and N or reduce the alkalinity. NSW is also very poor in soluble N and P, but the alkalinity is between ~6.5 - 7 dKH. If you desire to keep low nutrients like NSW, you need to keep alk low.
I hate to say this, but:
Trusting your live stock to a pet shop is tantamount to having a drunk pack your parachute.
You really should make your own water. It a very small tank, and it's just not that difficult.

I would imagine there are a number of responsible LFS owners who would disagree with you on this. Many also run tank maintenance businesses and know their stuff, so maybe paint with a smaller brush.

Good point, well taken. I don't think of a "Pet Shop" as the Local Fish Store. The LFS's Ive been to that do maintenance are usually fish only with a few herps, but there are shops I know who do sell pets and do a fine job with maintenance. That includes the LFS owner who took over part of my route, so again, point taken.
