Thanks, all. Gonna try ramping up slowly and keep an eye on the polyps. Appreciate the specifics on alk and calc too—helps to know I'm in the ballpark.

My Montipora aren't coloring up like they should. Running AI Primes at 60% for 8 hours, tank's 40 gallons, params are stable, 8.1 alk, 420 calc, 0 nitrates. What's the sweet spot for lighting these guys without frying them?
