Acropora of a wide variety do well with carbon dosing IME. Each system is different though and I don't know what's causing the browning and stn in your situation. backing off the dose might help . FWIW, I dose kalk 24/7 to maintain alk around 9dkh , pH at 8.1 to 8.35,calcium over 420ppm and magnesium over 1400. NO3 holds at less than 1ppm with PO4 in the 0.2ppm to 0.4ppm range. I also feed my fish heavily and quarantine new coral specimens for several weeks. Lighting is radium mh plus vho actinic for the main system with several ancillary tanks under leds
