I've also been feeding the fish a fair bit and adding aminos and BRS reef chili for the corals, just in case the corals were starving. This morning I had the best polyp extension I've had in weeks. Hopefully this means they're out of the woods.
Now what?...

the alk at 7-8 is only what some people noticed with acros whether this is true or not differs from person to person and there are still lots of people who carbon dose and have no issues with higher alk
i keep a dkh of 9 while i read zero for no3 and 0.006 for po4 so fairly low and have no issues with acros or hard corals in general
my system is carbon dosed with vinegar
so.........well now its time to go back to the basics its important to supply your demand for alk and calcium as there nothing else that adds to it , so monitor and add as needed.
don't make any drastic changes but change things that you feel you need to one at a time and monitor the results that ways you can find out whats sensitive or not in your system without having to guess.
glad to hear things are on the mend , fwiw its the rise in alk suddenly that hits corals hard , not just acros but most hard corals ....the drop can be as harm full if its as fast by allowing it to drop naturally and slowly the damage isn't near as severe
things should start to mend for you now again quickly
