NC2WA (what's your name? We go back and forth enough that I'd like to address you by something other than letters..
I think what is pushing me here is that this isn't ca, mg and alk.
There have been a lot of studies and articles lately noting that while we're currently at the point where we 'understand' the water requirements of corals, and we've gotten better at keeping them, we aren't providing for 'all' their needs. As I read 100's of threads around the web about browning or bleaching, or corals being generally unhappy regardless of the fact that params are where we want them, and lighting is sufficient, or tanks crashing at the drop of a hat even when its just a really short term (hours) type mistake.... then I read about the resiliency of corals in the wild coming back from crushing storms, and water temps, and oil spills.. I wonder if the fragility we see in our tanks is not only a water volume issue, but a missing piece to the puzzle.
I understand the hesitancy, and the need to keep things simple, I really do. But I also know that if we don't sometimes 'push the envelope', we stop learning. My tank(s) is/are awesome, and I have always enjoyed them regardless of the algae and the battles and the problems.
So, given that, I wouldn't advise everyone try this stuff, or anything other than really what you advised. But, I'm going into it with the understanding that this could all go terribly wrong and that not only could I end up with more problems than anything else, I could end up in a tear it down and start over situation because simple problems compound quickly in a reef tank. But I do enjoy the experiment part of it. And I try to formulate 'plans' such that I can keep things manageable if I do decide to try things.. Most of which I decided not to try. No algae scrubber, no bio pellets, no vodka dosing, no big jump into leds.. This is the first one that I've weighed out to feel like it was worth jumping on the 'band wagon' sooner rather than later. That wagon may lose wheels along the way, but regardless, it feels like it will be a fun ride..
