double check your calibration on salinityTemp is stable at 79 through the day and goes to 78 sometimes 77 at night.
Salinity is always at 1.025 I check it every morning and night.

Full intensity at what color setting though? I'm pretty sure it's got to be higher than that with full intensity and the blue turned all the way up. These things are a lot stronger than they look.
Not all sps need super high flow and light. Why not try some medium level light ones? Like a Branching Cyphastrea, Acro Echinata, Deepwater Aussi acro etc. If you have the other parameters of your tank locked in you can try lower light ones. If they live you know it could be not enough light that was your problem.

After reading the title, the first response in my head was "because they are stony corals" but I'll leave the smart-alec comments off the thread
I would say you have a combo lighting and flow issue. increasing both may help greatly. The rest looks good parameter wise.
I would also have to say to start making your own saltwater. You never know what you are going to get at the LFS. It's an unfortunate truth in the hobby that all LFSs are different. Yours may be good, but if you have issues, at least if you make your own, you have full control over it.
So he should try some more difficult corals? That just doesn't make sense.
I would check source water like the others have said. SPS aren't all that difficult compared to other corals, they're just not as forgiving. I would get some of the easy, bombproof sps to start with and see what happens. Get some monti caps, digitata, green slimer and or a couple birdsnest corals and see how they do. Once they start to take off, then look at adding more acropora.
The 2 best pieces of advice I received to keep healthy sps is to monitor alk religiously, and make sure you have the purest source water possible. I check alk EVERY friggen day! I don't skimp on RO production and products as well. Replace carbon and prefilters often and I run 2 DI canisters. One with a regular maxcap DI and a silicabuster DI both from spectrapure. Most importantly - don't give up!
I was just saying try some lower light SPS so it does make sense....
Some of the corals you suggested are no better then the ones I did. Birds nest as bombproof? really?
Speaking of not making sense it is over kill to test your alk daily and is totally not needed. You should learn to take a look at your tank and see the signs your corals give you when they need something. They give you almost all the feed back you need, experience will teach you that.
Lol.
Well buddy....We will have to agree to disagree on pretty much all that you just wrote. [emoji6]
