Looking for feedback

[Bergvid]

I'm having trouble with my acropora, i've been testing daily and monitoring all the levels but that's all in another post.

I'm just looking for feedback on how well my tank is suited for acropora and seeing if perhaps it's an issue with my tank/rock work. I've tried to aquascape bommies obviously I suck at it, none of the rock is glued so i'm open to changing it. Is my rock too low for my acro? I was hoping the coral would grow and fill out the space. I have 2 MP40's running full on Lagoon mode, the return pump is an M1 running 2 strokes off full and 3 radions, 2 are gen3 pro and 1 is a normal gen2 running on the sps coral labs 90% intensity. I have a heater temporarily in my display as the 2 eheim jaegers in my sump were not heating my water correctly (this was resolved months ago). My hammers are doing fine, I have lost a few pieces of acropora the blue tenuis on the top right and the tips of some other pieces have undergone necrosis

As of yesterday my levels were alk: 8.7, ca: 411, mg: 1500, phos: 0. This morning my alk dropped to 7.2 before dosing.

The tank has been running for around 1.5 years I just haven't gone to town on coral yet due to these issues.

Your rock work is fine, but you have room to add more. More rock = more surface space for bacteria and more mounting points for corals!

You have very few fishes.
This isn't very good for corals.
Fish poop is an important nutrient source to the corals. In the lack of that, dosing aminos/vit/micro elements is a way to go.

Plus, a drop of Alk from 8,7 to 7,2 in 24 hours is enough to kill some acros.

If the acros are dying from top down its either Alk burn or the lights are turned up too high for the acros. I actually run my LEDS at 100% on the blues peak and 35% on my whites at the peak.

That much of alk drop with few corals look strange.

Also,if P is really zero, that is a bad thing. Do you use GFO?
